Exchange 2013 P2P

Hi Experts, need to migrate a physical Exchange 2013 with all roles installed to another physical Exchange 2013 server. OS will be changing to 2012R2 on new server. What is the process to do this? I have reviewed http://exchangeserverpro.com/performing-like-like-exchange-server-migration/ this article. Is there any other information that would be useful

There are no plans to virtualize or to restore from backups so we are looking at alternate solutions

TIA

Install the server certificate immediately after the new server installed.
When 1st CAS server is unreachable it will search the netx avaialble CAS server.
If you are ready with certificate you are safe.

at first yes it might, that's why you should directly change the autodicsoveruri on the new one to match the one on the old one

once you do that you will not have any issues with autodiscover and you can finish your installation quietly

Check this to configure autodiscover. I missed this  in my above post. Thanks Akhater for pointing this missed point.

Guys, the certificate on the old server is a different name than the new server i.e. mail.domain.com versus exchange.domain.com. We would still like to use same OWA, can we reuse this certificate if names don't match?

You have to set the same URLs on both servers
Please check this to set the URLs
http://www.mustbegeek.com/configure-external-and-internal-url-in-exchange-2013/
Internal FQDN can be anything.internaldomain.com.
You can export and import the certifcate from old server to the new server.

Hi MAS, I have changed all services URLs on new server to match those of the old server. I have also exported and imported the cert to the new server but I am still getting an error with certificate when pulling from the new server. Do I need to regenerate? The cert does not contain name of new server and only contains name of old server in SAN

I am getting error message in Outlook. On clicking OK Outlook then connects to old Exchange server "There is a problem with the proxy server's security certificate. The name on the security certificate is invalid or does not match the name of the target site exchange.domain.com". Outlook is unable to connect to the proxy server (Error Code 10)
