I have written a number of Delphi applications that run on FB 1.5. I want to write new applications in, or migrate older ones to, FB 2.X. However, in the mean time I still need to be able to use and trouble shoot the legacy (FB 1.5) applications.

Can different versions of the Firebird client coexist on the 'client' side?

Can different versions of the Firebird server coexist on the server side?

Thanks
