Wildcard SSL

If I have an old SSL certificate from Verisign set up on serverA as:

mail.domain.com

And I need to put that on serverB, but I also need serverA to now have an SSL at this URL:

https://legacy.domain.com 

Is the easiest way to get a wildcard SSL? If I do that, do you think I'd have to get it through Verisign, or can I go with GoDaddy now? If I go with GoDaddy, do I need to "turn off" the old certs I have through Verisign?

For instance, I will still have an intra.domain.com through Verisign... but now the wildcard will overlap with that. Is that permitted?

GoDaddy sells UCC Certs with multiple names. That may be the solution to your situation.

There is no turning on or off of your certificates.  They simply get renewed each year unless you purchased multiple years.    You can revoke them. But if you have a paid cert now, can you just use that? If it is on a different server with the same domain, I think you just need to re key it.  

As for multiple servers, you need to check with the issuer.  Some will allow it.  I am pretty sure godaddy allows multiple servers with the same domain.

The SSL cert for 'mail' can be used on multiple servers if they respond to that name either through load balancing or fail over addresses.
All you need to do is to export the key from the live server and import it onto the other one.

If the main server is also going to have a different cert 'legacy' this can be installed as long as it is for a different product on a different port.
If the 'mail' domain name was serving smpt and pop3 (ports 25 and 110) then you could install the 'legacy' cert on ports 80 / 443 to allow it to be a web server.  These names then would not clash at all.
If you need both names to operate on the same port - for example both running web servers then you will need a seperate IP for each name.  You can add these to the same server (as long as you have multiple public IPs to do this with)

for your case I will not advise you to use wildcard SSL all you need is 2 or 3 SAN

I would advise you to issue a new certificate with mail.domain.com and legacy.domain.com and autodiscover.domain.com and then install it on your 2 servers

Thanks everyone. I ended up just moving the old Cert from old server to new, and then buying another cert for the old server to be "leagacy.mydomain.com". It worked out OK like that and I didn't need two certs on one server for what I needed to do.
