Hi!
We have migrated our Exchange 2003 to 2010. As per http://www.petenetlive.com/KB/Article/0000264.htm we can export the certificate from Exchange 2003 and import it in 2010 but is it really possible as the internal name of Exchange 2003 is different then 2010 and included as a SAN in the certificate. What is the proper way move the certificate. Should we generate a new CSR in Exchange 2010 and buy a new certificate.
Secondly, while generating a new CSR there is an option for legacy.domain.com. Should we include this in the new CSR. We need to decommission Exchange 2003.
Thanks.
