You must be aware of the SAN configurations that are transitioned by the 7-Mode Transition Tool. You should also be aware of the 7-Mode SAN features that are not supported in ONTAP, so that you can take any necessary actions before the transition.
You should verify all of the precheck error and warning messages to evaluate the impact of such configurations on transition.
The following SAN configurations are transitioned by the 7-Mode Transition Tool:
Instead, the required igroups are created during the cutover operation. For primary and stand-alone volumes, LUNs are mapped to igroups during the cutover operation. However, for secondary volumes, the mapping of LUNs to igroups is not supported during the cutover operation. You must manually map the secondary LUNs after completing the transition of primary volumes.
The unsupported configurations in ONTAP are as follows:
Snapshot copy-backed LUN clones present in the Snapshot copies are not supported for any restore operation. These LUNs are not accessible in ONTAP. You must split or delete the 7-Mode Snapshot copy-backed LUN clones before transition.
You must either change the value of the ostype parameter for such LUNs or delete the LUNs before transition.
You must either wait for the active LUN clone split operations to finish or abort the LUN clone split and delete the LUN before transition.
The following 7-Mode features enable you to continue with the transition process, but are not supported in ONTAP:
Sharing a LUN over NAS protocols
The following configurations must be transitioned manually:
You must manually create the LIFs before transition.
You must manually configure igroups that are bound to a portset after transition.
