Sorry for the late thank you, but, Thanks:) Decision was go with the SAN cert after all, just to avoid downtime (short as it may be) or any other issues.
Paul >Sure, you can do that. The disadvantage is that you'll have a short switchover timeframe during which the FE will probably not be accessible. (That is, the interval between when you put in the new certificate and update your DNS and then the DNS propagates to everwhere you need it to.) Using a SAN certificate containing the old and the new name avoids that. Regards, Michael B. Smith
