Hi Jeroen den Haan:
Thanks for posting.
The major compatibility issue with running FileMaker Server 11 on OS X Lion is web publishing will not work. This is detailed further in this article http://help.filemaker.com/app/answers/detail/a_id/9756 about FileMaker compatibility. If you plan to use FileMaker Server 11 for just ODBC and File Hosting, then you shouldn’t have any issues.
Thanks DSDuck, You say "shouldnt", but can you guarantee that? I'm looking for someone that actually runs Lion with FM Server and an ODBC connection. Or does Filemaker Inc have similar test units? With kind regards, Jeroen den Haan
Why are you in a hurry to use Lion? I'd definitely recommend waiting until FileMaker has released their patch for compatibility, and it has been tested for at least a week or two. Lion just doesn't provide any advantages for FileMaker Server (or much else server-wise).
