Hi James,
I'm just going to speak to the CCM question for now (pretty complicated) Just as an FYI CCM 4.2 has been announced as EoL (see below) I really like 4.2(3) but I just wanted you to know (you may already :)

For a CCM 3.2 to CCM 4.2;
This type of upgrade uses a multi-step approach to migrate the data from CCM 3.2 to 4.2(3). There are different considerations depending on whether or not the Servers are being replaced etc.
Upgrading Your Cisco Unified CallManager Server (When You Are Not Replacing Hardware)
You cannot upgrade directly from Cisco CallManager Release 3.2 or earlier to Cisco Unified CallManager Release 4.2. If your server runs a version of Cisco CallManager Release 3.2 or earlier, you must first upgrade every server in the cluster to the latest version of Cisco CallManager Release 3.3, 4.0, or 4.1 before you can upgrade to a version of Cisco Unified CallManager Release 4.2. For information on upgrading to Cisco CallManager Release 3.3, refer to the latest version of Upgrading Cisco CallManager Release 3.3.
Note If you are upgrading from Cisco CallManager 3.3, you must use the disks from the Cisco Unified CallManager 4.2(3) software kit.

If all you want from the 3.2 database is the phone/user info, you may be able to use the BAT Export from 3.2 and then BAT Import on 4.2. Be careful with the actual BAT format between versions as they will not match exactly for sure. With some tweaking this would probably work. Try some example Export/Imports to fine tune the .csv or BAT.xlt details before going for the lot.
Hope this helps!
