Exchange migration 2003 to 2010 next step
Posted on 2014-01-06
I am currently in the process of migrating exchange 2003 to 2010. my Exchange 2010 environment consists of 2 Exchange servers with all roles installed.
I have one DAG with 2 mailbox servers and 5 databases copied over the two mailbox servers.
I have migrated one Mailbox from the legacy server to the new server and it worked fine. I created send and receiver connector and it seems that incoming and outgoing emails are working.
I would like to know what's the next step that I can do now?
A friend of mine said that I have to update all the DNS records to Exchange 2010 and Exchange will handle the redirection of OWA site. but what about the CAS request for those who are still on Exchange 2003? would Exchange also redirect them too?
and what about Moving the OAB ? if I moved it would it affect the legacy mailbox users?
What about Upgrading Email Address Policies and Address lists ? would that affect anyone too?
Any notes to take on Moving Public Folders from Exchange? do I do them in a specific time?
Do I need to remove the Recipient Update Services after migrating all the users?
I would appreciate any comments.
Thanks a lot
