We have a bunch of (virtual vmware) windows servers (2003 and 2008) that our hosting provider wants to move to a new AD domain. They also want to rename the servers (just for the sake of introducing a new naming convention). The hosting provider is in charge of maintaining the servers, while we are in charge of making sure that all our business applications are working. Our business applications include custom developed .net applications using such things as SQLServer 2008, TFS 2010, asp.net, some legacy COM+ apps, etc.
To be honest I don't feel too convinced that this migration will be as painless as the hosting provider wants to make it sound. I would greatly appreciate any input on what we should be aware of when discussing the practicalities involved in the migration with the hosting provider.
Thanks in advance.
