If you copy your mnesia files from ejabberd 2.0.3, and start ejabberd 2.1.9 with those files, ejabberd will detect they are from an old version and will automatically update the tables as required, and will work correctly.

Hi badlop - I'm about to do a similar migration (2.0.3 to 2.1.9, but both on the same Linux host) and had the same question.

If you are an optimistic guy, copy the Mnesia database spool files and ejabberd.cfg file from 2.0.0-windows to 2.1.8-linux. Then start ejabberd and look at the log files.

In the best case, it will work immediately. In the worst case, it won't due to some problems (like diferent machine name, or problems in the config file), and you will have to check the error reports.
