mac | pc External Data sources (fmnet) with FileMaker 11

[sbbutkcin]

Has anyone had any luck with connecting the filemaker 13 databases with databases on FileMaker 11 using fmnet in external data sources? I tried to edit the existing references by adding .fp7 to the end of the filename and tried to create a new data source. However, when adding the remote server, it does not display any databases (as they are not compatible) and I unfortunately cannot convert them at this time.

They are not comparable, they are written in different languages.

Thanks Lee. I was really worried that was the answer. Appreciate your expertise.
