Migrate Your Access Database to MySQL—ODBC-Aware Mapping, Clean Types, Zero Data Loss
We move Microsoft Access tables to MySQL with deliberate type mapping, relationship preservation, and validation — ready for PHP and other open-source web stacks.
Serving businesses across the United States
Quick Answer
Migrating Access to MySQL means mapping tables through an ODBC-aware plan, converting AutoNumber and Access-only field types, rewriting Access SQL/VBA data logic, and validating in staging before cutover. Backend-focused projects typically take 2–5 weeks; a new web UI is scoped separately.

Signs You Should Migrate Access to MySQL
If the destination stack is open-source web, MySQL is usually the right engine — plan the type audit before the bulk load.
Migrate Access to MySQL Without a Naive ODBC Dump
MySQL Connector/ODBC makes it easy to push tables and hard to preserve meaning. We treat Access-to-MySQL as a schema and data-quality project first — AutoNumber, attachments, and Access SQL dialects — then move bytes.
Staying in Microsoft’s ecosystem? Prefer Access to SQL Server migration or compare every path on the Access database migration hub. Choosing MySQL because a PHP app is next is a valid reason — just budget the front-end rebuild as its own line item.
We can leave Access forms linked temporarily for a bridge period, but we will not pretend linked-table Access-on-MySQL is a permanent architecture for growing teams.
Our 4-Phase Access to MySQL Migration Process
Access Schema & ODBC Readiness Assessment
We inventory tables, relationships, queries, VBA, and Access-only field types. You get a written list of what maps cleanly, what needs redesign (Attachments, OLE, multi-value fields), and whether a linked-table bridge or hard cutover fits your downtime tolerance.
MySQL Model & Field Mapping
We design the MySQL schema: keys, indexes, character sets, and AUTO_INCREMENT strategy. Each Access column gets an explicit target type. Business rules encoded in Access queries are drafted as views or documented for the application layer.
Staging Load & Query Validation
We load into a staging MySQL instance while Access stays live. We validate row counts, orphan checks, and critical query results. ODBC linked-table smoke tests run if you need a temporary Access front end against MySQL.
Cutover, Index Tune & Handoff
We cut over off-hours, confirm backups and user access, tune slow queries exposed by real traffic, and hand off connection strings, schema docs, and a punch list for any web UI rebuild still ahead.
Microsoft Access vs. MySQL: Why Migrate
| Factor | Microsoft Access | MySQL |
|---|---|---|
| Cost | Desktop licensing; ops cost from corruption and locks | No per-seat DB license; hosting + DBA time are the real costs |
| Scalability | 2 GB file ceiling; degrades with concurrent writers | Grows with disk and server sizing; built for multi-connection load |
| Licensing | Access / Microsoft 365 | Open-source MySQL or vendor support subscriptions |
| Concurrent users | Roughly 10–25 practical concurrent editors | Hundreds of connections when sized and indexed correctly |
| Hosting | Windows file share / VPN | Linux/Windows servers, managed MySQL, or cloud DBaaS |
| App stack fit | Desktop Access / VBA | Natural fit for PHP and other open-source web apps |
| Type strictness | Tolerates messy types and multi-value fields | Requires deliberate mapping; cleaner long-term data |
Backend migration cost above assumes schema, data move, and validation — not a full PHP application rewrite. If you need both, we price the database move and the web rebuild as separate scopes so MySQL does not look “cheap” until the UI work appears mid-project.
Who We Migrate Access Databases to MySQL For
Our clients are US-based teams moving off Access toward open-source web stacks — especially PHP — or Linux-hosted MySQL. Typical work sits in the industries we cover under industry solutions.
- Small businesses replacing Access with a MySQL-backed web app
- Retail and ops teams standardizing on Linux/MySQL hosting
- Manufacturers whose next MES or inventory UI is not Microsoft-only
- Agencies and IT teams handed an .accdb that must feed an existing MySQL application
- Teams that tried a raw ODBC export and need a clean relational repair
Access to MySQL Migration: Frequently Asked Questions
How do I migrate an Access database to MySQL?
You audit Access data types and relationships, map AutoNumber to AUTO_INCREMENT, replace Access-only field types, export or ETL into MySQL, rewrite Access-flavored SQL and VBA data logic into standard SQL (or application code), then validate counts and critical queries before cutover. ODBC is a connector — not a full migration plan by itself.
Can I transfer an Access database to MySQL myself with ODBC?
MySQL Connector/ODBC can link or export tables, and a small flat database can transfer with careful type mapping. Once you have Attachment fields, OLE Objects, multi-value lookups, AutoNumber quirks, or VBA-driven rules, a DIY ODBC dump usually creates MySQL tables that do not enforce the relationships Access implied — that cleanup is cheaper before cutover than after a PHP app is already live on bad data.
What is Access to MySQL ODBC migration?
ODBC lets Access link to MySQL tables or push data through the MySQL Connector/ODBC driver. Linked-table setups can keep Access forms temporarily while MySQL holds the data. Permanent migrations still need schema design, type conversion, index strategy, and a plan for forms/reports — ODBC alone does not rewrite VBA or Access queries.
Will Access forms keep working after a MySQL migration?
Sometimes, via linked tables, for a transition period. Linked Access-on-MySQL is a bridge, not the end state for most teams — performance, SQL dialect differences, and unsupported field types show up under load. Long-term, forms usually move to a PHP, Node, or other web front end, or you choose SQL Server / Power Apps inside Microsoft’s stack instead.
How long does an Access to MySQL migration take?
Backend-focused migrations (schema, data, validation, optional Access linked-table bridge) typically take 2–5 weeks. Adding a new web front end is a separate rebuild and stretches the calendar. Row count matters less than Attachment/OLE cleanup, query rewrites, and how much VBA encodes business rules.
Will I lose data migrating Access to MySQL?
No — we stage imports, compare record counts and key checksums, and keep Access online until you approve cutover. Fields with no MySQL equivalent (Attachments, OLE Objects, multi-value lookups) are remapped explicitly — file storage, JSON, or child tables — so they are not dropped by a naive export.
How much does it cost to migrate Access to MySQL?
Backend migration and validation for a small-to-mid Access database commonly falls in the $2,500–$12,000 range at $90/hour with a fixed-scope quote after assessment. A full PHP/MySQL application rebuild on top of that data is a larger project and should be priced as application development, not only a database move.
How many concurrent users can MySQL handle vs Access?
Access is a file database with roughly 10–25 practical concurrent editors. MySQL is a client-server engine that routinely supports hundreds of concurrent connections when sized and indexed correctly — subject to hosting, query design, and connection pooling. That concurrency jump is why teams leave Access for MySQL under a web stack.
Should I choose MySQL or SQL Server when leaving Access?
Choose SQL Server when you want to stay in the Microsoft stack, keep Access forms linked longer, or use SSMA. Choose MySQL when the target app is PHP or another open-source web stack and you want to avoid SQL Server licensing. We map both against your hosting and developer skills in the free assessment — see also our Access to SQL Server path if Microsoft is the constraint.
What Access data types break in MySQL?
Attachment, OLE Object, and multi-value lookup fields have no clean one-to-one MySQL type. Memo/Long Text become TEXT/LONGTEXT, Yes/No becomes TINYINT or BOOLEAN, and AutoNumber becomes AUTO_INCREMENT with care around existing keys. We produce a field-level mapping document before any production load.
Can MySQL replace Access for reporting?
MySQL stores and serves the data; reporting usually moves to a web report layer, BI tool, or scheduled exports. Access reports do not migrate automatically. We inventory each report and assign it to SQL views, application reports, or a BI tool so operations still get month-end numbers on day one.
Do you migrate Access queries and VBA to MySQL?
Saved Access queries become MySQL views or stored routines where they fit; domain aggregates and Access-specific functions get rewritten. VBA that manipulates data is ported to SQL, application code, or scheduled jobs. UI VBA goes away with the Access forms unless you keep a temporary linked-table front end.
