Similar procedure, limited amount of people.

It should be a rare exception not a normal thing, so a few people is fine.

Best practice is to also have your change reviewed beforehand, and run in a transaction where you also validate expected results before committing, etc.

Yep there should be a rollback plan, a change review process prior to running it and successful tests from a test system (which should be identical to prod)
