Why Do Businesses Migrate?
The most common reasons we've seen:
Enterprise requirements - Many large enterprises standardise on Microsoft SQL Server across their entire infrastructure. If you're selling to enterprise clients or integrating with enterprise systems, MSSQL compatibility becomes a requirement.
Existing IT infrastructure - Some businesses already run Windows Server environments and SQL Server licenses. Running MySQL alongside adds unnecessary complexity.
Reporting and BI tools - Microsoft's reporting and business intelligence tools integrate far more naturally with MSSQL than MySQL.
What Actually Changes
Most developers assume it's a simple export-import. It rarely is.
- Data types don't map 1:1 between MySQL and MSSQL
- Auto-increment syntax is different
- String functions have different names and behaviours
- Stored procedures need to be rewritten
- Date handling works differently
What We Do Differently
We map every table and column before touching any data. We write conversion scripts that handle edge cases. We run parallel systems - old and new - before cutting over. And we test with real data, not sample data.
A migration done wrong corrupts your data. A migration done right is invisible to your end users.
If your business is considering a database migration, don't treat it as a simple task. Get it done right the first time. KeyTech has the experience to handle it properly.*
