Using multiple SSL certs for exchage 2010 and 2007

Hi,

We are currently in the process of migrating from exchange 2007 to 2010.  We are working on the SSL cert we will need for our environment.  Our current SSL cert for our 2007 servers is expiring shortly and the question was raised whether we can renew that cert with one SSL provider while for the 2010 servers generate a new SSL cert with a different provider.  I dont see why this would not work as the 2007 servers will be gone in less than 6 months and we only want to renew that for one year.  Our 2010 servers we will purchase for 3 years.  If someone could confirm this would work without any issues it would be appreciated.

thanks!

Hello,

In order to maintain proper client connectivity during the transition, you are going to need a new certificate that contains names similar to the following names:

mail.domain.com
autodiscover.domain.com
legacy.domain.com

See the following for details on how to transitions and the certificate requirements: http://blogs.technet.com/b/exchange/archive/2009/11/20/3408856.aspx

Yes.  I understand that.  I just want to make sure I can use 2 separate SSL certs from 2 separate providers.  Our 2007 environment is a comodo cert which is up for renewal and our 2010 environment we will be moving to verisign.  All the domain names are covered under one or both of the certs.  As an example... our legacy.domainname.com will be on the comodo cert (exchange 2007) but will not be on the 2010 cert (verisign).  I assume that still will not be an issue
