We want to migrate our Exchange 2003 server to exchange 2013. We found that direct migration is not possible from exchange 2003 to exchange 2013 so we need to migrate first Exchange 2003 to exchange 2010 and then again migration to exchange 2010 to exchange 2013.
We want to keep both new exchanges in a VM.
Right now we have two exchange server 2003 on site and we need to move with both exchange server 2003 to exchange 2013. Furthermore we need to configure exchange failover.
What will be the best practices and implementation design/scenario.
