Migrate WPMU site to new host

Hi

Does anyone have any advice for migrating a WPMU 2.8.6 install to a new ISP host.

My process;
1. Disable user login (No modifications to blogs) - OLD Host
2. Configure default settings on new host (as per http://trac.mu.wordpress.org/browser/trunk/README.txt),
2a. Setup DNS on new host.
2b. (NOTE) DNS takes 24 hours to propagate.
3. Backup all WPMU files
4. Backup WPMU DB
5. Restore WPMU Files and DB on new Host
6. Test / check once DNS has propagated
7. If tests successfull, enable end user logon.

Is there anything i am missing? or any further advice?

Thanks in advance
