Can R11 UPM exist with R12 or 12 with 12.5 etc..What about the upgrade scenarios?
UPM versions and DSM/ITCM versions must always match, regardless of whether it is a new install or an upgrade:
UPM:11.2 SP4 gets paired with DSM 11.2 SP4, ITCM 12.0 gets paired with UPM 12.0 and the same for 12.5? dissimilar versions are not supported.
