If you get an error while importing, it's probably because the cert you are importing has the same name as an existing cert. Just add something to it, like a 1 or something.
On the previous certificate, in the Used By column there are two options: Web Admin and Web Auth
Open one at a time and change the dropdown for 'Trustpoint' to the new certificate you have imported.
Make sure you are clicking these little dudes:
For Web Admin the field is on the left under HTTP Trust Point Configuration.
For Web Auth you must click global before seeing the dropdown next to Trustpoint
