Step 2 sounds dodgy.  How do you know server A's additional products are 
compatible with Plone 2.5 ? or even 2.1 and above?

If they're 3rd-party, check for later versions.

If they're your own, check for customisations that might break it, as 
described in http://plone.org/documentation/migration/2.1

You might try doing this whole process skipping step 2, or parts of step 
2. That way you can narrow down to the offending product thats causing 
it to break.

One other thing of note.
Zope 2.7.3 to Zope 2.9.3 may be a big jump , and not tried by many people.

You might try migrating to Plone 2.1.3 on Zope 2.8.7 first. This has 
been done by a lot more people , so the code has been more exercised (or 
should I say, "exorcised"  ;-)  )
