you could that but you could also ISL 9222i's to 9216i, allow all zoneset/zones to propagate to 9222is and then as you migrate systems/storage to 9222i, decommissions 9216i's. Take a look at Cisco documentation, specifically full zoneset distribution.
I plan to migrate all our Windows and VMWare ESX Hosts from two Cisco MDS 9216i fabric switches to two new Cisco MDS 9222i switches. I have two question Can I backup the VSAN zones on each of the MDS9216i switches and restore them to new VSans and zonesets  that I create in the MDS9222i switches in order to recreate the same zoneset configuration with zones,storage and device aliases?
