Nataraj,

You are in the kind of situtation that requires biteing the bullet so to
speak. If you truly need to update, I would recompile and tweak the Delphi
1.0 app bring it up to 32-bit. and then make a copy of the database in FB or
IB6 work with it until it works maybe using IBObjects.

then once fully debugged. One weekend , go in and copy the data into the new
DB and install the client on every machine while leaving the old in so they
can use it in an emergency or just for reference.


I cannot see how you could do otherwise if you truly want to do it in a
professional, responsible manner. This is what is so bad about taking a
legacy installation the people who have it must be made to understand that
upgradeing is a necessity
