We have had a change of domain name. This means that all my servers will have to move from xxx.domain1.busininess to xxx.domain2.businessAre there any best practices or guides available for this. We have a number of AGS servers clustered and this is federated to a Portal server. We also have a datastore server and a geoevent server. So all content will need the domain name changing. Machines will need to be renamed, rejoined to our domain with the new name and subsequently rejoined to the site as the new name.
