Thank you both for the replies. Yes, i've made sure our db backups are being captured daily but will ensure i have a clean set before i start with the upgrade. I know we've saved off backups of the certs & keys in past workplaces & kept them offsite in case of a disaster, so it sounds like i need to make sure that is happening here as well. I'm pretty sure it is but will confirm with the lead DBA here. Thx again for the feedback. That's what i needed to know.
