we have to upgrade a lot of Interbase 5.6. databases to Firebird 1.5.

1) is it save to deinstall IB5.6 then install firebird 1.5 and then
backup and restore all the ib5.6 databases with firebird 1.5?

or do i have to backup with interbas 5.6 and restore with firebird?

2) how can i get the version of the client-dll the application loads.
i use ibobjects. i couldnt find any routine to to query the client
version. i want to know wether my app loads the interbase or the
firebird client dll.
