I need to migrate an actual fabric based on Cisco 9124 and 9134, to a brand new Cisco Director 9506. Actually I have two fabric (fabric 1 and 2) which are not currently merging together. VSAN are not in use in the actual scenario.
I would like to move to a VSAN topology. In order to proceed with migration from actual fabric, my idea would be to create two separate VSANs on the 9506 (VSAN 10 and VSAN20). Then I could merge fabric 1 with VSAN 10 and fabric2 witrh VSAN20. Unfortunately I can't use IVR, then the idea would be to disable trunking on ISLs so I could migrate zones to new directors but maintaining the separation between fabric 1 and 2 (from actual physical separation to new logical one). I am aware merging different VSANs is discouraged, but it is documented by Cisco ("In some cases, you may need to merge traffic from different port VSANs across a non-trunking ISL. If so, disable the trunking protocol. "). Idea would be maintain the ISL for the time required to migrate all the gears (servers and disk arrays) to the new directors. My question then: have you got any experiences or suggestions ? Could I proceed with this unusual merge hoping not encounter any outages ? Many thanks !
