Along with all its new features, FileMaker Pro 12 has changed the file format for its databases from .fp7 to .fmp12. If you have a database that was created using any previous version of FileMaker Pro, you’ll need to convert the file before you can open it with any edition of FileMaker 12. FileMaker 12 does the converting: Both FileMaker Pro 12 and FileMaker Pro Advanced 12 can convert files created with versions 7 through 11.
If you have databases created with FileMaker Pro 1 or 2, you’ll need to dig out a copy of FileMaker Pro 6 and convert them to that format first, then convert them to .fp7 using FileMaker Pro 11. Once that’s done, you can convert your databases to fmp12 format.
Before FileMaker Pro 12, it was perfectly fine to have some users running FileMaker Pro 10 while others used FileMaker Pro 11 to connect to the FileMaker Server 11. So long as the file formats matched, you could get away without upgrading everyone’s software at once.
