gufo-thor migrate-mongo¶
Migrate the MongoDB Feature Compatibility Version (FCV) to the version required by the configured NOC release. MongoDB is upgraded one supported FCV at a time, using the matching MongoDB image for each step.
Synopsis¶
The command reads the current FCV from the Thor state file. If no FCV is recorded, it assumes the legacy FCV 4.4. It then migrates through each supported FCV up to the target configured for the selected NOC version, saving the completed FCV after each step.
