I've started work on a fairly major system using IBO 4.2, Delphi 5,
and Firebird 1.0, only to discover today that the customer already
has Interbase 5 installed and in use. (I did ask before I started;
they didn't know it was there.) The IB5-based software is from a
major vertical market vendor and it's the most important thing my
customer uses, so I can't disturb it and nothing's going to change
but me.

I need some advice; it crosses the lines between IBO and
Interbase/Firebird questions, but I'll start in this group:

- How much trouble am I going to have developing in FB1.0 and
deploying in IB5? Are there many basic differences? (About the most
sophisticated SQL I use is some sub-selects and some unions).

- I need to use their copy of GDS32.dll, right? But no other changes
to my software?

- To deploy my DB, I'm planning to take a transportable backup of my
database to their system and restore it using the IB5 software, right?

- (Since I'm not installing anything other than my database file to
their server) There's no chance I'm going to mess up their critical
IB5-based program, right?

- Am I into any licensing issues? They have enough "seats" of the
other software (and thus I'm assuming of IB5) to cover every PC in
the place, so I'm not breaking any licensing agreements, right?

Thanks for any advice,
