Exchange 2010/2013 SSL certificates

We're in the middle of a dual swing migration from Exchange 2003 to Exchange 2013: Just finished the Exchange 2010 install on a "spare" Server 2008 box, and will be moving the mailboxes (there are only 25, total) this weekend. I had planned on doing my CSR and installing the SSL certificate, but wondered if I would be able to move it to the Server 2012R2/Exchange 2013 server in a week or two, when we do the second step of the dual swing migration.

So, basically, can I purchase an SSL cert for the Server 2008/Exchange 2010 box, and move it to the Server 2012R2/Exchange 2013 in a couple of weeks?

Thanks, in advance, for any input!

Regards,

Ric J.

I won't recommend immediate migration on Exchange 2013 from Exchange 2010 because you just migrated everything from Exchange 2003 let it run for a month at least to see if there is no issue anymore. then you can uninstall Exchange 2003 because without removing Exchange 2003 you won't be able to install Exchange 2013.

So once you are done with buying certificate then there is no issue whenever you want to change certificate you can create CSR and get it signed.

Agree with Amit.
Furthermore you can rekey/reissue your certificate when you install Exchange2013 server.

Check this to get the command for CSR.
