Hi there,

I have a situation where I have sharepoint 2013 on a certain domain name and have installed sharepoint 2016, but would like to use the same domain name for that as well. I'm not sure if it is possible to have 2 certificates with the same subdomain but different port numbers ?

Say

https://sharepoint.xyz.com:3001/ = sharepoint 2016
https://sharepoint.xyz.com:4001/  = sharepoint 2016

Its a bit of an odd query, however I'm not ready to turn off sharepoint 2013 yet for multiple reasons

Kind regards

JK

That is not different sub-domains, that is different ports.  I don't think that can work.  Maybe if the IP address is the same...

Can a single SSL server certificate cover multiple ports per domain name?
Yes, a single SSL server certificate can cover multiple ports for the same domain name. As an example, the certificate for myserver.mydomain.com will work for:
https://myserver.mydomain.com; and
https://myserver.mydomain.com:8888

i hope u got the answer..

SSL certificates are based on the hostname i.e. you certify that that machine is the real server. You can use same SSL for any or all port(s) on your server
