Steps
Break the data protection mirror relationship by using the snapmirror break command.
The relationship is broken and the disaster protection volume becomes a read-write volume.
Delete the existing data protection mirror relationship, if one exists, by using the snapmirror delete command.
Remove the relationship information from the source SVM by using the snapmirror release command.
(This also deletes the Data ONTAP created Snapshot copies from the source volume.)
Create a SnapVault relationship between the primary volume and the read-write volume by using the snapmirror create command with the -type XDP parameter.
Convert the destination volume from a read-write volume to a SnapVault volume and establish the SnapVault relationship by using the snapmirror resync command.
(Warning: all data newer than the snapmirror.xxxxxx snapshot copy will be lost and also: the snapvault destination should
not be the source of another snapvault relationship)
