Guidelines for transitioning SnapLock volumes
You can transition 7-Mode SnapLock volumes to SnapLock volumes created in ONTAP 9.5 or earlier. You must be aware of the requirements and guidelines for transitioning SnapLock volumes.
Transition of 7-Mode SnapLock volumes is not supported if the SnapLock volumes contain LUNs.
You can transition 7-Mode SnapLock Enterprise volumes only to SnapLock Enterprise volumes in ONTAP 9.5 or earlier.
You can transition 7-Mode SnapLock Compliance volumes only to SnapLock Compliance volumes in ONTAP 9.5 or earlier.
When transitioning a 7-Mode volume SnapMirror relationship, you can use staggered transition (transition secondary first and then primary) only for SnapLock Enterprise volumes.
SnapMirror disaster recovery (DR) relationship between 7-Mode primary volumes and ONTAP secondary volumes is supported only for SnapLock Enterprise volumes, but not for SnapLock Compliance volumes.
You must transition a 7-Mode volume SnapMirror relationship between SnapLock Compliance volumes by transitioning the primary and secondary volumes in parallel.
