Octopus Deploy uses the Master Key to encrypt and decrypt sensitive values in the Octopus Deploy database. Back them up once to a secure location and move on to the standard upgrade process. The master key doesn’t change, while your license key changes, at most, once a year. It is better to have the backup and not need it than need the backup and not have it.
