Thanks Sean,
but what if the old server isnt present any more and we have to
upgrade old databases?
the background is: our customers get a application update with
firebird 1.5 included. so interbase will be uninstalled. some
customers may have several hundreds or even thousands of databases!
and we cannot asure they made a backup of all their databases.
so we have to upgrade (backup/restore) with firebird. in our tests the
interbase databases seem to be ok after a backup/restore with firebird!?
So: is it really neccessary to backup with ib5.6?
What can go wrong if we backup interbase-databases with firebird?
