Exchange - New domain - Two SSL Certs

[CapnPugwash]

Hi, we've recently changed our external domain name (mynewschool.mycounty.com) . The old domain name (myoldschool.mycounty.com) will remain live for two months.

 

On our exchange server we have an SSL cert installed for the old domain, this works fine. I've now been sent a PFX file for the new domain. Can I import the PFX and leave the old SSL cert on there as well or do I need to delete it?

 

Thanks in advance

Ah... it looks like I can only 'Assign services' to one certificate - sorted!
