Why not 2.6.2?

well, it's a big upgrade, a lot has changed, especially 2.1 -> 2.2.

Take care of those issues first and make sure the site works on 2.2.  
If you're lucky those will be the only problems and you can then go 
straight from 2.2 to 2.6.2.

If you're feeling really cautious, you might consider going
through the whole cycle of major releases (last / best version of each one).
Note that I can't vouch for whether this is necessary or even harmless :-)
E.g. upgrade to each of these in turn:

Zope-2.2.5
Zope-2.3.3
Zope-2.4.4
Zope-2.5.1
Zope-2.6.2
