I'm going to conduct a migration of approximately 1000 users on Exchange 2003 to 2010. and I would like to know if there's any step by step guide with snapshots on doing so.
The customer has has 1 exchange 2003 app server and 3 database servers. So according to the existing environment I would like to know the following
How many Servers do I need for each of the following roles?
1- Mailbox servers,
2- Client Access Server,
3- Unified Message server,
4- Hub Transport Server,
5- Edge Transport server.
I would so much appreciate your inputs and since this is the first time I'm doing this kind of migration I would appreciate any notes from someone who have already applied this migration.
I would like to also know how many public certificate do I need for the exchange and where will it be installed exactly?
What are the required SANs for the certificate(s)?
Just for the info, I have done Exchange deployments but not migrations.
Thanks a lot
