We've got a client who changed its Company Name just after the migration of 2010 => 2013.
All mailboxes are moved to 2013. Now we need to change their external/internal urls without user interruption...
Current config:
2 x Windows 2012 R2 + Exchange 2013 RU7 => 1 DAG => 2 databases (primary & archive)
External urls:
activesync.currentcompany.be
autodiscover.currentcompany.be
Internal urls:
Exchange2013.currentcompany.be
DNS records:
autodiscover SRV record for newcompanyname.be
Accounts:
Login@newcompanyname.be
New config:
Same servers
External urls:
activesync.newcompanyname.be
Internal urls:
exchange2013.newcompanyname.be
What is the best practice for this?
