Powerpath migration enabler from VPLEX to VMAX

Hi,

We are trying to migrate the storage for Windows 2016 SQL Cluster from VPLEX to VMAX through Powerpath 6.1 but we are getting below error.

PPME error(79): Not all nodes have reached the correct state to complete this operation, please try this or the recover command again later

We have two node in main site and two node in DR site connected through VPLEX and we need to migrate to VMAX..

Please let me know the best method in order to migrate the cluster with zero downtime.

Regards,

Hakim. B
