I've built an Exchange 2010 Environment consisting of two Mailbox servers and two combined hub/cas servers.
We also have an existing Exchange 2003 environment(single server).
I understand you can use the "Exchange2003Url" paramater to redirect users still with 2003 mailboxes to the old 2003 OWA.
The existing external address is https://owa.lon.companyname.com
and SSL secured.
My plan is to create a new UCC cert with the same common name and the required SAN names(including names for the old 2003 exchange). This will revoke the old cert on the 2003 server I assume.
Will I be able to install that UCC cert onto the old 2003 server so when users get redirected there are no cert issues.
