Hello,

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?

Thanks

Once you get the new cert you'll install it on the Exchange system in the normal way, then you'll export it with the private key.

Then on the UAG box, you'll import this exported file via the certificates mmc placing it in the local computer store - make sure you also install any intermediate certificates the vendor may require.

On the UAG you'll need to edit any published services that use the certificate - and select the new one. The old certificate can stay there, it does no harm.

Cheers Keith! Should I rename the old ones friendly name in the MMC? As I remember the UAG dropdown menu for certificates is pretty plain(no expiration date or other unique info). What do you usually do in regards to this? After that, do you just activate the config in UAG or do you also perform IISRESET on the UAG server?

Personally? I remove the old certificate completely. I do rerun the Activate config routine - just in case the TMG supplied with the UAG has used the certificate in any of its own listeners (you may want to check a 'before and after' yourself just to be on the safe side) but I also reboot the UAG. A reboot of the Exchange services should not be necessary.
