Delphi 7 to delphi2007

We have several apps in Delphi 7, one com app in delphi 4.  We are looking
to upgrade them to somethng current/supported, ex Delphi 2007.   These would
be just win32 client apps, no web/dot.net  What is generally required to
move from Delphi 7 to Delphi 2007?  Is this feasible. Is there any
information on what is required to upgrade.  Can the source code just be
imported and then adjust for de-supported functions etc?  Guess I was
looking for any gotcha's that people have run into. I am trying to come up
with a time estimae. I hear the IDE requires .net?

Thanks
Mike

Very. The major problem source are 3rd-party controls, code just using
the RTL or VCL will usually compile without any changes. If you use
conditional compilation depending on compiler versions (VERxxx symbols)
this needs to be updated, of course.

If you have source for your 3rd-party controls the runtime part will
also usually build without changes, but the designtime part can be a
bit more demanding, depending on which features of the open tools API
it uses.

Yes, but the installation contains all required prerequisites.
