Good Morning Experts,
We have a Exchange 2007 Enviorment. I have my new Exchange server 2010 server up along side of 2007. Some of the users are getting SSL security warnings that are from the new Exchange server.
My installing the needed certs was planned but here is what I don't understand.
Our full migration is happening over Christmas and then we will demote the 2007 Exhange.
We already have purchased the appropriate certifications for our 2007 server so do I need to purchase double if they are going to co-exist? We already have a cert designated for our mail.domain.org so I am confused if I need to purchase additional certs for this limited time, or the alerts will just happen until I complete the migration process. I am hopeful I can just transfer them over.
Thank you for your help.
