Porting Applications from WebSphere to WebLogic?

JFP queries: "I work for a division of a manufacturing company. We're currently running IBM WebSphere 3.5. We are considering a switch to BEA WebLogic 6./7. Has anyone had luck with IBM's upgrade path? Has anyone else ported a WebSphere 3.5 application to WebLogic? If so, how much of code did you have to rewrite? Are there any 'gotcha!'s that you ran into that you would care to pass along?"

How is this for ports.

1) Perl
2) ATG Dynamo
3) MS .NET

All in about 2.5 years.

I think the site would best be served from Perl creating static web pages, sorta how Salon does it. Oh well.
