15 Signs It's Time to Leave Microsoft Access

How to use this: if you check off three or more of these, it's genuinely time to start planning a migration — even if you're not ready to execute yet.

Not every Access database needs to be replaced. Plenty run safely for years with the right maintenance. But there's a real pattern of warning signs that show up when a business has outgrown what Access was ever designed to handle. Go through this list honestly — most people underestimate how many of these already apply to them.

Version and Support Signs

• You're running Access 2016 or 2019 (already unsupported as of October 2025)
• You're running Access 2021 and haven't planned for its October 2026 end of support
• Nobody in your organization can say with confidence which version you're actually running

Performance and Reliability Signs

• The database has become noticeably slower over the past year
• You've experienced database corruption at least once in the last 12 months
• Forms or reports occasionally time out or freeze, especially with multiple users active
• Backups require everyone to log out first — and that's becoming harder to coordinate

People and Knowledge Signs

• One specific person is the only one who really understands how the database works
• That person's departure, retirement, or extended absence would be a genuine crisis
• The system has little or no documentation of its logic, relationships, or quirks
• New hires need significant hand-holding just to use the system safely

Growth and Scale Signs

• You need more than a handful of people working in the database simultaneously
• Team members work remotely or across multiple locations and need access outside the office network
• Your data volume has grown substantially since the system was first built
• You've built manual workarounds to connect Access to other tools (QuickBooks, a CRM, reporting software) because it doesn't integrate natively

What to Do With This List

A checklist like this is meant to prompt an honest conversation, not deliver a verdict on its own. If you've checked several boxes, the next useful step is usually a real assessment of your specific database — its actual size, its actual risk points, and a realistic view of what migrating would involve.

From there, the two most common paths are moving to Power Apps for a modern, mobile-friendly rebuild, or migrating the backend to SQL Server if your data volume and reporting needs are the primary driver. Either way, the process itself follows a similar shape — see our step-by-step migration overview.
