It is not possible since 2.5 introduces incompatible changes. If you need to move from 2.5 back to 2.1, the only way would be to copy data from one database into another. I tried this in the past and met with another problem: which version to use to access the databases for copy. IIRC, 2.5 did alter the database structure so I could not use it with 2.1. The final solution was to start up the source database on 2.5 server and prepare a clean database on a different machine with 2.1 server. And then I copied the data using FBCopy tool. To prepare a clean database, you can use something like "isql -x" to dump the database schema from 2.5, and then run that script on an empty database with Firebird 2.1. Good luck. -- Milan Babuskov ================================== The easiest way to import XML, CSV and textual files into Firebird: http://www.guacosoft.com/xmlwizard ==================================
