No such thing as a downgrade, closest thing is to rollback to whatever version is in the inactive partition (losing all the changes made after switching the partition)

Bear in mind that if this is a new purchase, the licensing is version specific and pre-12 uses PLM while 12+ uses smart licensing.

Hello baechangmin,
kindly note that the downgrade concept is not supported on CUCM.
you can switch versions in between the active and inactive partitions.
and no lower version can be uploaded to the CUCM than the current on the both partitions.
Regards,
