Correct, run these steps before you connect it back to your core.
hi Folks,  Cisco MDS 9513 (switch name : A-55) was in production (ISLed to core ) but due to changes in the environment we had to move the director A-55 from one room to another in the same datacenter, as a process we blocked the ISLs and powered down the switch and configured the New ip address and are now trying to bring them into production again in other words merge with core again. So in this regards are there any specific steps to be followed like remove the zonesets/zone from the director A-55 to make a clean merge or anything like that of ?  can you please assist in the steps for a clean merge?   Note: A-55 has NO connections/links to the Host or Storage arrays before or after except the ISLs to the cores.  Thanks in Advance
Cisco MDS 9513 clean merge into production?
