Hi there, <br />
<br />
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 ? <br />
<br />
Say <br />
<br />
https://sharepoint.xyz.com:3001/&nbsp;= sharepoint 2016<br />
https://sharepoint.xyz.com:4001/&nbsp; = sharepoint 2016<br />
<br />
Its a bit of an odd query, however I'm not ready to turn off sharepoint 2013 yet for multiple reasons<br />
<br />
Kind regards<br />
<br />
JK

HTTPS is a protocol for secure communication over a computer network which is widely used on the Internet. HTTPS consists of communication over Hypertext Transfer Protocol (HTTP) within a connection encrypted by Transport Layer Security (TLS) or its predecessor, Secure Sockets Layer (SSL). The main motivation for HTTPS is authentication of the visited website and to protect the privacy and integrity of the exchanged data. HTTPS is widely used for protecting page authenticity on all types of websites, securing accounts and keeping user communications, identity and web browsing private.
