Like a lot of folks, my recovery site is populated with older hardware. And now we've come up on an issue where the ESXi hosts at the recovery site can not be upgraded to the same ESXi version as the protected site (protected site = 5.5 U2, recovery site = 5.1 U3).
The vCenter at the recovery site is the same as the vCenter in the protected site (5.5 U2), and the SRM at both sites is the same (5.5).
Question: that should be OK, right? as long as the vCenter and SRM versions at both sites are the same, I can have different versions of the ESXi hosts, without a problem? (presuming I keep an eye on the VMtools version, and the virtual hardware versions of the VMs, so I don't use anything that isn't supported at the recovery site)
Thanks
