Converting a single file
Use the single-file conversion method for standalone database files that don’t display related data from other files. See Converting a single file.
1. If the file you want to convert is currently open in the previous version of FileMaker Pro, close the file.
2. Start FileMaker Pro 15.
3. In the My Solutions tab in the Launch Center window, click Browse.
If you don’t see the Launch Center window, choose File menu > Open. In the My Solutions tab, click Browse.
4. In the Open File dialog box, select the file to convert, then click Open.
The Conversion dialog box appears, where you can choose to rename the existing file prior to conversion. By default, FileMaker Pro does not rename the file.
5. Do one of the following:
To skip renaming the old file, make sure the Rename old file checkbox is cleared, then click OK. It’s not necessary to rename the old file if it includes the .fp7 filename extension, because your converted file will have the .fmp12 extension.
To rename the old file, select Rename old file. Either accept the default name (which is the original filename appended with “Old”), or enter a new name. Then click OK.
Note  If a filename includes a period (.), other than the one that precedes the filename extension, remove it. If a period exists in a filename, FileMaker Pro won’t add the .fmp12 extension to the converted file.
6. In the Name Converted File dialog box, enter the filename that you want for the new file.
7. Click Save to start the conversion.
You can save time by clicking Skip when the index is being re-created, which postpones indexing until later.
8. Using a text editor, open the Conversion.log file located in the folder that contains your converted database.
