I have assigned new ssl cert installed on our exchange, for some reason windows 10 tablets are having issues.
we want old cert to be extended , it has been issued by our internal CA.
CAN we EXTEND IT for one year ? with private key
also if we extend it and some thing goes wrong , can we reuse the old cert back again if we take a back up which we are extending having original dates. or cert itself will change and cant reuse the old one
if we extend the current cert1 having expiry in dec 2016 to dec 2017 and something goes wrong
can we resue the old cert having expiry which was till dec 2016
