Are there any requirements specific to SnapLock aggregates that must be met before 7toC transition?

Last Updated:

Applies to

  • 7-Mode to Cluster Mode (7toC)
  • SnapLock Enterprise (SLE)
  • SnapLock Compliance (SLC)


  • A major design change from 7-Mode is the like-to-like transition between regular, SLE, and SLC volumes.
  • This change means SLC can transition only to SLC, and SLE can transition only to SLE.
  • Non-SnapLock to SnapLock transitions or vice versa fail.
    • Error log example:

ERROR Initialize from source volume '' to destination volume 'svm1:vol8' failed with error 'Transfer failed.'. Relationship UUID 'xxxxxxxx'.
ERROR       replication.dst.err: SnapMirror: destination transfer from to vol1 : destination volume must be a SnapLock Compliance volume.

  • In the case of SLC volumes, snapmirror resync is not allowed if it results in the loss of data at the resync destination.
