    Legacy 4.1, 5.0, 5.5 migration to 6.5U2

      Hi. I have a customer that has around 20-30 legacy (out-of-support) 4.1-5.5 ESXi hosts (around 900 vm's). The underlying SAN is iSCSI and running very old storage OS (legacy VNX). The customer cannot upgrade the storage OS to support 6.5U2 (long story). Therefore, upgrading the ESXi hosts is not going to work, as the storage would be unsupported.


      Question - The VNX can storage replicate to another VNX (at second site). If the second site is running ESXi 6.5U2 hosts, would it be as simple as replicating the legacy vm's (that reside on the 4.1, 5.0, 5.5 ESXi hosts) from site one to site two, and then mounting the replicated LUNs (datastores) to the ESXi 6.5U2 hosts? Basically, could we facilitate the migration of all legacy vm's to new ESXi 6.5U2 hosts via storage replication only? Once again, there doesn't look like there is an opportunity to upgrade the legacy ESXi hosts due to underlying storage incompatibility.
