Migration from Builder 2 to 3

Question

Greetings!
Imported two projects from builder 2 into builder 3. One
project is simply a module whose builder path is into the second
parent app.
When running the app, I first got an error:
Argument count mismatch on mx.binding::PropertyWatcher().
Expected 3, got 2.
I switched the compiler from Flex 3 to 2.0.1 hotfix 3. Now,
I'm getting the error:
VerifyError: Error #1014: Class mx.modules::Module could not
be found.
The module is clearly bulding into the parent app bin folder
as specificed in properties. Whats worse, I can no longer open
either project in builder 2. I'm hosed.
Suggestions?

I know this is an old topic, but just in case anyone else
finds there way here. It looks like the opensource part of Adobe
has usurped flexunit,
this article is the needful

There is a link for the SWC but it is old, below will save
you a click.

You should remove all your old FlexUnit libraries and replace
with the one FlexUnit.swc (originally flexunit.swc). You will have
a minor difference in the TestRunner.mxml, just grab the one form
the above blog.
