Our entire office is moving to a new building. This new building will merge two companies, each with their own AD domain. In order to start fresh, we are implementing a new domain, with new services (Exchange 2010, BES 5.0, Domain Services, etc.). We currently have a SharePoint 2007 (Version: 126.96.36.19920) that we want to keep, but we want it to become a member of this new domain.
What are the easiest steps we need to do to get this done?
The SharePoint server is currently a VM, can we make changes and if it doesn't work, can we restore a backup of the VM?
In this new domain set up, we will be upgrading our SQL Server from 2005 to 2008 Standard R2. Would you recommend we keep the SharePoint database on SQL Server 2005 or is it easy to migrate the DB to SQL Server 2008?
