Git flow feature in branch on stage server
If you switch from the feature branch back to develop, it won't wipe them out because the changes are stored in the database, and you should see an overridden status on the feature. Once you switch back to develop, you can perform a feature-revert again to change the settings back.

Either way, I would backup the database, either using Backup &amp; Migrate, or directly on the server, just in case anything goes wrong.
