WARNING: You are about to create a migration relationship between the source LUN and target LUN. Migration starts immediately after the relationship is established, and the data on the target LUN will be overwritten by that on the source LUN after the migration.
Suggestion: Before performing this operation, ensure that the selected source LUN and target LUN are correct and the target LUN is not being read or written by hosts. If the capacity of the target LUN is larger than that of the source LUN, scan for the source LUN again after the migration is complete.
