I am going to change the SSL cert used for publishing exchange, already ordered a new one. How is the best practise for this in regards to backing up the existing(going to expire) SSL cert and using the new one. Can the old be renamed or will I have to delete it? Can I simply import the new one into certificates mmc on the UAG server and pick it up using the UAG console? Any kind of iisreset needed? Does anyone have a good, easy, simple link that explains this process?
