Dear Friends,
We have exchange 2007 SP3 with CU13 installed with single copy cluster for database and 1 OWA server for CAS/HT. We will migrate from current to Exchange 2013SP1. As we want to have HA, we have installed 2 new Exchange 2013 SP1 CAS server on widnows 2012 R2 after preparing our organisation for Exchange 2013. The setup went smooth without any error and successfully installed CAS with management tools. After installation it ask to reboot the server which we did. Now after reboot, we are not able to run Exchange Management Sell. It never connects to the new server. In our old 2007 EMS also doesn't list any exchange 2013 server. We are also not able to connect to new CAS servers with below URL:
https://servername/ecp/?ExchClientVer=15
Its says site under maintenance. Please advise what to check. We were thinking of deploying CAS 1st and make it co-exist with Exchange 2007 before deploying Exchange 2013 mailbox server which will be setup in DAG. What are we doing wrong.
Thanks in advance!!
