Converting a FlexVol volume SnapMirror relationship to a FlexGroup volume SnapMirror relationship

To convert a FlexVol volume SnapMirror relationship to a FlexGroup volume SnapMirror relationship in ONTAP, you must first convert the destination FlexVol volume followed by the source FlexVol volume.

1. Verify that the SnapMirror relationship is healthy: snapmirror show

   Only XDP type mirror relationships can be converted.

   Example

   cluster2::> snapmirror show
                                                                          Progress
   Source            Destination Mirror  Relationship   Total             Last
   Path        Type  Path        State   Status         Progress  Healthy Updated
   ----------- ---- ------------ ------- -------------- --------- ------- --------
   vs0:src_dpv DP   vs2:dst_dpv  Snapmirrored
                                         Idle           -         true    - 
   vs0:src_xdp XDP  vs2:dst_xdp  Snapmirrored
                                         Idle           -         true    -
   
2. Verify whether the source volume is compatible for conversion:
   1. Log in to the advance privilege mode: set -privilege advanced
   2. Verify the conversion process: volume conversion start -vserver vs1 -volume src_vol -check-only true

      You must rectify all errors before converting the volume.
3. Convert the destination FlexVol volume to FlexGroup volume.
   1. Quiesce the FlexVol SnapMirror relationship: snapmirror quiesce -destination-path dest_svm:dest_volume

      Example

      cluster2::> snapmirror quiesce -destination-path vs2:dst_xdp
      
   2. Start the conversion: volume conversion start -vserver dest_svm -volume dest_volume

      Example

      cluster-1::> volume conversion start -vserver vs2 -volume dst_xdp
       
      Warning: After the volume is converted to a FlexGroup, it will not be possible 
      to change it back to a flexible volume.
      Do you want to continue? {y|n}: y
      
      [Job 510] Job succeeded: SnapMirror destination volume "dst_xdp" has 
      been successfully converted to a FlexGroup volume. 
      You must now convert the relationship's source volume, "vs0:src_xdp", to a FlexGroup. 
      Then, re-establish the SnapMirror relationship using the "snapmirror resync" command.
      
4. Convert the source FlexVol volume to FlexGroup volume: volume conversion start -vserver src_svm_name -volume src_vol_name

   Example

   cluster-1::> volume conversion start -vserver vs0 -volume src_xdp
    
   Warning: Converting flexible volume "src_xdp" in Vserver "vs0" to a FlexGroup
            will cause the state of all Snapshot copies from the volume to be set
            to "pre-conversion". Pre-conversion Snapshot copies cannot be
            restored.
   Do you want to continue? {y|n}: y
   [Job 57] Job succeeded: success
   
5. Resync the relationship: snapmirror resync -destination-path dest_svm_name:dest_volume

   Example

   cluster2::> snapmirror resync -destination-path vs2:dst_xdp
