Hello   An upgrade from version 9.11.1p8 to version 9.12.1p3 was being performed and this failed with the error: Failed to migrate data life from node "controller-01"   The controller-02 was left with version 9.12.p3 and the controller-01 with version 9.11.1p8, and it does not allow me to update it since it gives an error that the HA is not active due to the firmware difference.   It is possible to manually update controller-01 only and leave it at the same version.   If so, they will have the process.   Thanks for your help ...
