steps of changing domain from .local to .com

I have several windows servers including a Remote Desktop services server. My internal domain is setup as a .local however now my SSL certificate from Godaddy will not renew for my remote apps because it has the .local name in the SAN. Their support told me I need to remove it and rename my domain to one of my .com sites. I have gmsmrm.local and What are the steps and side effects of making this change?
I also run AD sync with Office 365 with an azure server. Will this be effected as well?

you don't have to do anything with the server itself.  

As long as resolves to the gmsmrm.local address you'll be fine.  Note you MAY need to implement split DNS (eg: you have your own DNS server for the internal networks) that may have a internal IP versus the public ip.

Does AD Sync run off of the .com currently or the .local?

You were right. I added to my SAN SSL certificate and applied it to my RDP server and it works! I didn't have to do anything to my local domain. However this leads me to believe that I may want to change .local down the road.
