Hi all,
We have Exchange 2007 infrastructure as below:
1. MBX\CAS\HUB installed on one server
2. UM server
3. Edge server
We need to migrate to Exchange 2013 as below:
1. MBX\CAS on one server
2. Edge server
However, I am not sure if we can use the same certificate we are using right now for Exchange 2007 (3rd part CA)?
Regards,
