Hi,
I'm planning an Exchange 2007 migration to 2013 and I'm trying to wrap my head around co-existence scenarios. Our 2007 environment uses the FQDNwww.companyemail.com for OWA (etc) and I'd like to have our 2013 environment use something more standard like webmail.company.com
The MS documentation I've seen deals with retaining/reusing the original FQDN, but can I do a co-existence scenario and introduce a new namespace? Any high-level pointers or advice would be great.
Greg
