"local databases" - is this mysql or text based databases?

B.t.w.: Saving emails as text files lets me hope that after upgrade of the 
imap service or even OS upgrade one day, the old backups stay usable?

I am asking this because I once got into big trouble when I had to move 
multiple mysql databases to a new machine with new OS and new version of 
mysqld. - Nothing worked and I had to use mysql-dump to export the data as 
text-dump on the old system and import them into the new one.
After that, the permission system also had to be set up from scratch 
because of different data format...

Best regards,

Markus
