Before you convert any FileMaker Pro database, you should plan the conversion carefully. The general steps for file conversion are:
FileMaker Pro 12 can only convert files created with versions 7.x, 8.x, 9.x, 10.x, and 11.x. (To convert files earlier than FileMaker Pro 7, see
Converting FileMaker Pro databases earlier than version 7.x.)
When you convert files, FileMaker Pro 12 preserves the contents of your original files and creates new, converted files in FileMaker Pro 12 format. The content of the original files are not modified, and you can open them in the previous version of FileMaker Pro that created them. The converted files can be opened only in FileMaker Pro 12.
