When setting up Exchange 2003 it was necessary to run ForestPrep (extend AD schema) and DomainPrep (to Prepare the domain for Exchange). At the time these were Win2K3 Servers. Now, I am migrating my DCs to newer hardware and with Windows Server 2008 R2 (64-bit). What, if anything needs to be done once I've migrated the DC servers or will these changes move during the migration?

Technical correction: ForestPrep doesn't extend the schema, SchemaPrep does. All those things apply to Active Directory, which stays the way it is when you upgrade your hardware, unless you blow away your AD and start over, which I wouldn't advise you to do.-- Ed Crowley MVP"There are seldom good technological solutions to behavioral problems.".

Technical correction: ForestPrep doesn't extend the schema, SchemaPrep does. just wanted to make things clear, In e2003, Schema expantion is done by /forestprep, there is no seperae switch to do so then later with exchnage 2007 or 2010, to make the permissions very granular, MS included seperate switches. /ps - prepare schema alone /pl - prepare legacy permissions /p - prepare AD/Pd - prepare a domain/pad - prepare all domain in the forest Note: /p can also run /ps if we didnt ran that exclusively finally to answer his question..Forestprep and domainprep are make changes to the AD (in the Schema, configuration and Domin partitions) via a DC when replication happens the changes wouldbe repliated to all other DCs in the Forest.Hari

You are right. Microsoft keeps changing things and confusing me.-- Ed Crowley MVP"There are seldom good technological solutions to behavioral problems.".

You don’t need to run these commands, DC replication will take care of it as Hasiv said above.
