I would say take a backup of the database before hand. Then typically these installs are replace some .dll files. I always just rename them to olddll.date so if we need to revert back we can. Also you need to stop the required services. There should be install directions with the release.

MRs usually do not affect the database but why chance it.
Always back up the database to be on the safe side.
