If you are not satisfied with the performance of your clustered Data ONTAP LUNs, you can rollback from clustered Data ONTAP to Data ONTAP operating in 7-Mode for copy-free transitions \(CFTs\). Rollback is not supported for copy-based transitions \(CBTs\). Rollback is only supported on certain hosts.

Rolling back LUNs to 7-Mode after transition

If you are not satisfied with the performance of your clustered Data ONTAP LUNs, you can rollback from clustered Data ONTAP to Data ONTAP operating in 7-Mode for copy-free transitions (CFTs). Rollback is not supported for copy-based transitions (CBTs). Rollback is only supported on certain hosts.

You can rollback from clustered Data ONTAP to Data ONTAP operating in 7-Mode at any point before you click commit in the 7-Mode Transition Tool (7MTT). After you click commit, you cannot rollback.

The following hosts support rollback:
