Hi all.
I'm valutating to migrate from an old Delphi 3 to Delphi 7. My main project
have about 220 units and about 190 forms. Do you think can i have a lot a
problems to make that?. I use a lot of add-on library like Orpheus (an '97
old version 2.14), rx lib, xceed zip and other all with source ecc. some
suggest or link to get information about that? mainly the migration is for
use crytal reports 9.
thaks a lot from Italy.

It sounds like you already understand the issues here. 3rd party
components will probably be your biggest problem. While it's possible
for you to make the old component source work under D7 you're probably
better off trying to get the latest source from the respective vendors.
At the point I'd just make a complete copy of the program, load it into
the D7 IDE, and see what happens. You'll fairly quickly be able to
assess what the problems will be.

Depends on the quality of your code <g>. D3 to D7 is a major hop, but if you
have source for all your 3rd-party components it should not be too bad. You
may find yourself adding "Variants" to a lot of uses clauses, though.

You can get the last version from http://turbopower.sourceforge.net, TP made
it open source when it went out of the component/library business.
Is now part of the JEDI VCL, see jvcl.sourceforge.net
