This is a post that would have been better served had you posted it in the FileMaker Pro section rather than Report an Issue. Not only can you create a database in FileMaker 11 with the same characteristics, you can use FileMaker 11 to open and convert your FileMaker 6 file to FileMaker 11 format. There will likely be few issues that need to be fixed after the conversion, but often this is easier than starting over from scratch.
For more on the subject, search the Knowledge base (Pull down the Support menu at the top of your screen), using the key word "migration" and specify FileMaker 11 as the application.
Following your advice, I had no more problems with converting my art archive from 6 to 11!
I would expressly thank you, because your help was better than I found in the "Missing Manual"
Have a nice weekend.
Kind regards. André Henkemans
