I have written an RCP application that contains numerous plugin-ins I have created using Ganymede version 3.4.2. I want to start using Galileo. When I try to execute my RCP application from the Workspace I created using Ganymede I get lots of errors like the following:

Why is upgrading from one Eclipse version to the next so painful?
Is there a systematic way of resolving the above issues?
Is there a "best practices" upgrade procedure available?
Thanks for your help.
After trying what VonC suggested I am still experiencing some problems. This is the constraint part of the MANIFEST.MF for the RCP application: Bundle-RequiredExecutionEnvironment: JavaSE-1.6 Require-Bundle: org.eclipse.core.runtime;bundle-version="3.5.0";resolution:=optional;visibility:=reexport, org.eclipse.ui;bundle-version="3.5.0";resolution:=optional;visibility:=reexport, org.eclipse.core.expressions;bundle-version="3.4.100";resolution:=optional;visibility:=reexport What is the significance of the "visibility:=reexport" and "resolution:=optional" parameters? Error messages: org.eclipse.core.databinding Missing Constraint:Required-Bundle: org.elclipse.core.databinding.observable;require-version="[1.2.0.2.0.0]" Missing Constraint:Required-Bundle: org.elclipse.core.databinding.property;require-version="[1.2.0.2.0.0]" Same two messages for: org.eclipse.jface.databinding org.eclipse.ui.workbench

The error you listed says that Galileo doesn't see all the plug-ins and libraries Ganymede and your program was using. Sorry for the non-answer below. Your alternative is fiddling with Galileo until it sees all your libraries and plug-ins.
What I would do is install Galileo side-by-side Ganymede and port your applications over one at a time. I'm assuming you are working under Windows, but the same techniques that I list here also work for Linux.
First, in theory, all you have to do to upgrade from Ganymede to Galileo is install Galileo over Ganymede. Believe that? Good. I don't either. So walk through Ganymede and note what plug-ins you have installed. Then install Galileo in a separate directory. Point the new install at your Java VM. Then install all your plug-ins. It's your choice how you do this.
Finally, I'd differentiate between source and Meta in your projects. Create a new project under Galileo and move only your source. Let Galileo re-build your meta.
Now, how to avoid all this pain next time: Version control. CVS, SVN, git... it doesn't matter what you use. Eclipse has a plug-in that supports them all. Then, next upgrade, simply import the source into a project in your new Eclipse installation. Much less painful, and you'll have much more control over your source.
Good luck.
