Access Database Migration — United States

Migrate your Access database to SQL Server, the cloud, or anywhere it needs to go.

SQL Server, Azure SQL, MySQL, PostgreSQL, Dataverse, Power Apps, .NET, or SharePoint — we migrate the data, rebuild the forms and reports that depend on it, and keep your business running the entire time. No lost records, no guessing which platform fits.

Quick answer

Migrating an Access database means moving your tables to a real database engine (most often SQL Server) and then either keeping your Access forms as a lightweight front end, or rebuilding them on a new platform — Power Apps, Dataverse, or a custom web app. Which path is right depends on your user count, budget, and how much of Access's VBA logic your business actually depends on.

Choose your migration path

Eleven ways to move on from Access — and when each one actually fits

There's no single "correct" destination. Below is the real trade-off for each path, written the way we'd explain it in a scoping call — not a sales pitch for one platform.

01 · ACCESS → SQL SERVER

Migrate Access Database to SQL Server

Migrating Access to SQL Server means moving your tables to a SQL Server backend while your Access forms and reports keep running as a linked-table front end — the fastest, lowest-risk first step off a struggling Access database.

This is usually where a migration starts, even when SQL Server isn't the final destination. Microsoft's free SQL Server Migration Assistant (SSMA) or the built-in Upsizing Wizard moves tables, relationships, and indexes automatically, mapping AutoNumber fields to IDENTITY columns and rebuilding your primary/foreign keys.

Your existing Access forms, reports, and most VBA code keep working against linked tables, so the immediate problems — corruption, the 2 GB size ceiling, and "database is locked for editing" errors — go away without a full rebuild. You can retire the Access front end later, on your own timeline, or keep it indefinitely as a lightweight client.

  • Access front end can be phased out later — it's not required to be

02 · ACCESS → AZURE SQL / CLOUD

Migrate Access Database to Azure SQL & the Cloud

Moving Access to Azure SQL uses the exact same migration path as on-premises SQL Server — the difference is where the database lives, not how it's structured — giving you remote, multi-location access without VPNs or in-office servers.

Azure SQL Database speaks the same T-SQL dialect as on-premises SQL Server, so schema mapping, key types, and query logic transfer directly. What changes is operations: automatic patching, geo-redundant backups, and the ability to scale storage or compute up (or down) without buying hardware.

For teams with remote staff, multiple offices, or contractors who currently email .accdb files around, this is often the single highest-impact change — everyone connects to one live, always-current database instead of passing a file back and forth.

03 · ACCESS → MYSQL

Migrate Access Database to MySQL

Migrating Access to MySQL is possible via ODBC connectors and export tooling, but because Access's SQL dialect, AutoNumber fields, and VBA logic don't map one-to-one to MySQL, plan for a data-type and query audit before the data moves.

MySQL Connector/ODBC lets you link or export Access tables directly, but a few Access-specific data types — Attachment fields, OLE Objects, multi-value lookup fields — have no native MySQL equivalent and need a deliberate replacement strategy. AutoNumber becomes AUTO_INCREMENT, and Access-flavored SQL functions in queries and VBA get rewritten in standard SQL.

MySQL is the common choice when Access is being replaced by a PHP-based or other open-source web stack, largely because there's no per-seat database licensing to account for.

  • Requires a data-type mapping audit (Attachments, OLE, lookups)
  • VBA business logic must be rebuilt in the new application layer

04 · ACCESS → POSTGRESQL

Migrate Access Database to PostgreSQL

PostgreSQL migration follows a similar path to MySQL, but its stricter data typing and constraint enforcement tend to surface years of accumulated Access data-quality issues during the move — which is inconvenient up front and valuable long-term.

The psqlODBC driver connects Access to PostgreSQL for linking or bulk export. Because Postgres enforces types and constraints more strictly than Access ever did, migrations routinely turn up mismatched dates, orphaned foreign keys, and inconsistent text entries that Access silently tolerated for years — worth fixing once, not carrying forward.

PostgreSQL is a strong backend choice when the rebuilt application needs complex reporting, geographic/spatial data (via PostGIS), or heavier analytical queries than a typical line-of-business app.

05 · ACCESS → LIBREOFFICE BASE

Migrate Access Database to LibreOffice Base

LibreOffice Base is a free, open-source alternative to Access that can import your tables directly — a genuine option if per-seat Microsoft licensing is the actual problem, though queries, forms, and VBA macros don't come across automatically.

Base's import wizard reads Access tables directly and brings over basic structure and data with minimal setup. It runs on an embedded database engine (Firebird in current versions, HSQLDB in older ones) for a self-contained file, or can connect out to MySQL, PostgreSQL, or any ODBC/JDBC source if you need a shared, multi-user backend instead.

The honest limitation: Base's forms, reports, and macro environment aren't Access clones. Macros run on LibreOffice Basic, not VBA, so real automation logic gets rewritten rather than ported, and the forms/reports tooling is noticeably less mature than Access's. It's the right call when the goal is eliminating license costs on a modest, well-understood database — not when Access's VBA layer is doing heavy lifting.

06 · ACCESS → DATAVERSE

Migrate Access Database to Microsoft Dataverse

Dataverse is the managed, cloud-native data platform behind Power Apps and Dynamics 365 — migrating here trades your local .accdb file for a governed, secure, multi-user database with row-level security and an audit trail built in.

Your Access tables and relationships get re-mapped into Dataverse's entity model, which is a genuine data-modeling exercise, not a straight lift — Dataverse has its own conventions for lookups, choice fields, and relationships. In exchange, you get enterprise-grade security roles, full audit history, and native integration with Power Automate, Teams, and Outlook.

This is Microsoft's actual, currently-supported modern successor to Access as a business application platform. It requires Power Apps/Dataverse licensing, which is worth budgeting for early.

  • True multi-user cloud database — no more "locked for editing"
  • Built-in security roles, permissions, and audit trail

  • Requires Power Apps/Dataverse licensing — plan it into the budget

07 · ACCESS → POWER APPS

Migrate Access Database to Power Apps

Power Apps replaces Access's forms and screens with a modern, responsive front end — typically running on a Dataverse or SQL Server backend — making it the closest like-for-like upgrade to Access's biggest weak point: its dated, desktop-only UI.

Think of Power Apps as the app layer and Dataverse (or SQL Server) as the data layer beneath it. For line-of-business apps of moderate complexity, this combination gets you mobile-friendly, browser-based forms without a from-scratch custom build.

Where it has limits: heavily custom VBA logic, complex calculations, or deep integrations sometimes need Power Automate flows or custom connectors alongside it, which adds design work up front but keeps the whole thing low-code.

  • Complex VBA logic may need Power Automate flows or custom connectors

08 · ACCESS → .NET / WEB APP

Convert Access Database to a .NET or Custom Web Application

Converting Access to a .NET, PHP, or other web application is a full rebuild: your tables move to SQL Server, MySQL, or PostgreSQL, and your forms, reports, and VBA logic are rebuilt in real application code — with no Access license or runtime required for anyone using it.

There's no automated "convert" button here, and any tool claiming otherwise is describing an export, not a migration — Access forms and VBA don't have a mechanical equivalent in web code. This path is a genuine software build: data layer first, then business logic, then UI, then testing.

It's the highest-effort option and the highest ceiling. You get full control over authentication, roles, integrations with other systems via APIs, and a system that scales to any number of concurrent users without ever touching an Access runtime again. The same approach applies whether the target framework is .NET, PHP, Node, or Python — only the application layer changes.

  • Full control over UI, security, and third-party integrations
  • Scales to any number of concurrent users
  • Highest effort — right for genuinely business-critical systems

09 · ACCESS → SHAREPOINT

Migrate Access Database to SharePoint

Microsoft retired Access web apps (Access Services) in 2018, so "migrating to SharePoint" today means one of two things: linking Access to SharePoint lists as a lightweight backend, or moving the whole application to Power Apps + Dataverse, which is Microsoft's actual modern successor.

This trips up a lot of otherwise-good migration plans, so it's worth stating plainly: if you're looking at old guidance describing Access web apps published to SharePoint Online, that feature no longer exists. SharePoint lists can still serve as a simple, shared backend for small, low-complexity Access apps — but they come with row-count and throttling limits that matter once you're past a few thousand records.

For anything beyond a simple shared list, Power Apps on Dataverse (with SharePoint as an integration point, not the database itself) is the path Microsoft actually supports going forward.

10 · ACCESS → EXCEL

Convert Access Database to Excel

Exporting Access data to Excel is a two-minute built-in task (File → Export → Excel) — but it produces a report, not a migration, since it drops relationships, validation rules, and business logic along the way.

For a one-off report, a pivot table, or sharing a snapshot with someone who doesn't have Access, the native export is genuinely the right tool — no third-party converter needed, and no cost.

The pattern worth watching for: if your team is exporting to Excel weekly to work around what Access can't do well, that's usually the clearest sign it's time to migrate the underlying database rather than keep patching around it in spreadsheets.

11 · ACCESS → PDF

Convert Access Database to PDF

Converting an Access database to PDF is a built-in, one-click export for any table, form, or report — but it's a static document, not a live database, so nothing beyond that report's data comes along with it.

Access's native Export to PDF or XPS tool (File → Export → PDF or XPS) turns any report, form, or table datasheet into a shareable PDF in seconds, preserving the layout your report was designed with. For a one-time handoff to a client, auditor, or someone without Access installed, this is genuinely the fastest option available.

If PDF exports are something your team needs on a recurring basis — end-of-month statements, invoices, batch reports — Access's OutputTo method in VBA can automate the same export on a schedule, without anyone opening the report manually. What it can't do is turn Access into a system other people can query, filter, or update; for that, the data itself still needs to move to a real database.

How it works

The same disciplined process, whichever platform you land on

  1. 01

    Discovery & audit

    We inventory every table, relationship, query, form, report, and line of VBA — so nothing gets left behind or discovered mid-migration.

  2. 02

    Target platform selection

    We walk through the trade-offs above against your team size, budget, and timeline, and land on the right destination together — not the one that's easiest to sell.

  3. 03

    Schema & data migration

    Tables, relationships, keys, and data types move to the new backend, with validation passes to catch anything that doesn't map cleanly.

  4. 04

    Rebuild forms, reports & logic

    Forms, reports, and VBA business logic get rebuilt for the new platform — from a linked-table front end to a full custom application.

  5. 05

    Testing & validation

    Side-by-side comparison against the original Access database, record counts, calculations, and edge cases included.

  6. 06

    Cutover & support

    A planned go-live with a rollback path, plus training so your team is confident on day one — not left to figure it out.

Frequently asked

Access migration questions, answered plainly

What's the best way to migrate an Access database to SQL Server?

For most databases, Microsoft's free SQL Server Migration Assistant (SSMA) or the built-in Upsizing Wizard is the right starting point — it moves tables, relationships, and indexes automatically. Your Access forms and reports can then keep running against linked tables while you decide whether (and when) to replace the front end entirely.

Can I convert an Access database into a web application?

Yes, but "convert" is a rebuild, not an automated file conversion — Access forms and VBA don't have a mechanical web equivalent. The typical path moves your data to SQL Server or PostgreSQL, then rebuilds the forms, reports, and business logic as a real .NET, Power Apps, or other web front end.

How do I migrate Access to MySQL or PostgreSQL?

Both use ODBC drivers (MySQL Connector/ODBC or psqlODBC) to link or export Access tables. Plan for a data-type audit first — Access-specific fields like Attachments, OLE Objects, and multi-value lookups don't map directly, and AutoNumber needs to become AUTO_INCREMENT (MySQL) or a SERIAL/IDENTITY column (PostgreSQL).

Can I convert an Access database to a PHP web application?

Yes — it follows the same path as any custom web rebuild. Your tables move to MySQL or PostgreSQL, both of which pair naturally with PHP, and your forms, reports, and VBA business logic get rebuilt as PHP application code. There's no automated Access-to-PHP converter, for the same reason there isn't one for .NET: the forms and macros don't have a mechanical equivalent in web code.

What is SSMA?

SSMA (SQL Server Migration Assistant) is a free official Microsoft tool that automates schema and data migration from Access into SQL Server or Azure SQL — mapping tables, keys, relationships, and many queries. It doesn't touch your Access forms, reports, or VBA code; those still need separate handling.

Can Access still connect to or migrate to SharePoint?

Microsoft retired Access web apps (Access Services) in 2018. Today, Access can link to SharePoint lists as a simple shared backend for low-volume data, but that comes with row-count and throttling limits. For anything more substantial, Power Apps on Dataverse is Microsoft's actual current successor.

How do I convert an MDB file to ACCDB?

Open the .mdb file in a current version of Access and use File → Save As → Access Database (*.accdb), or the "Convert Database" command. This only updates the file format (.mdb is the Access 2003-and-earlier format); it doesn't fix underlying performance, size, or multi-user limitations, since it's still the same database engine.

Is there a free way to convert Access to Excel?

Yes — use File → Export → Excel directly inside Access, no third-party tool needed. It's ideal for one-off reports or sharing data with someone who doesn't have Access, but it produces a static snapshot, not a live, relational, multi-user database.

Can I convert an Access database to PDF?

Yes — use File → Export → PDF or XPS on any report, form, or table datasheet, no extra tools needed. VBA's OutputTo method can automate the same export on a schedule for recurring reports. Either way, it produces a static document, not a live database someone else can query or update.

Can I migrate an Access database to LibreOffice Base?

Yes — Base's import wizard reads Access tables directly, and it's a genuinely free, cross-platform option if licensing cost is the real problem you're solving. Plan on rebuilding forms, reports, and any VBA automation by hand, since Base uses LibreOffice Basic macros instead of VBA.

Will my forms, reports, and VBA macros keep working after migration?

It depends on the path. Migrating just the backend (to SQL Server, for example) usually lets existing forms and reports keep working through linked tables, with minor adjustments. Migrating to a genuinely different platform — Power Apps, Dataverse, or a custom web app — requires rebuilding forms and reports, and porting VBA logic into the new application's code.

What happens to my Access queries when I migrate to a real database?

Most Access queries translate into either database views or stored procedures on the new platform, and straightforward select/filter queries usually convert with minor syntax changes. Queries that lean on Access-specific SQL functions or VBA-driven dynamic SQL need to be rewritten by hand, since those functions don't exist outside Access.

Do I need to migrate my entire Access database at once?

No — the most common approach upsizes just the backend first (tables move to SQL Server while your existing Access forms and reports keep running as a linked-table front end), then replaces the front end on its own timeline later, if at all. A full rip-and-replace in one step is usually reserved for databases moving to a genuinely different platform like Power Apps or a custom web app.

What's the difference between migrating Access to Azure SQL and to on-premises SQL Server?

Functionally, very little — both run the same T-SQL engine, so schema, keys, and most queries transfer identically. The real difference is operational: Azure SQL is a managed cloud database with automatic patching and backups and no hardware to maintain, while on-premises SQL Server runs on a server you own, patch, and back up yourself.

How long does an Access migration take, and what does it cost?

It depends on table count, form/report complexity, and how much VBA logic is involved. A backend-only upsize to SQL Server can take one to four weeks; a full custom web application rebuild typically runs six to sixteen-plus weeks. Because every Access database is different, we scope cost and timeline after a short audit rather than quoting blind.
