Question regarding UCC SSL Certificate

[dlp]

Our company is currently in the process of a name change, so I'm tasked with keeping the old stuff running and also get the new company stuff running. Our current UCC SSL certificate which the CN is set to the old company name is set to expire soon, so I went ahead and purchased a new UCC SSL certificate.

I'm getting ready to do the CSR for the certificate and I was wondering if I use the new company name for the CN and just put the old company names in as a SAN, if I would run into any browser warnings or errors when accessing the webpage or exchange server, owa of the older company?

So, basically new SSL cert will have CN=www. newcompanyname.com

SAN
mail.oldcompany.com
autodiscover.oldcompany.com
www. oldcompany.com

Thanks!

That will not work unless you get a Multi-Domain Certificate. They can get to be pretty pricy depending on how many SANs you are looking to cover. Hopefully, your company will let you get rid of the old name after a year. Also not sure of your Cert provider, but that will also determine price and eligibility and depending on your company and how many public facing services you offer, a Mutli-Domain Cert may actually be more cost effective and less of a headache to keep up with.

Thanks, for the reply! I did purchase a multi domain cert. I installed it last night and everything is working as it should.
