Our current VMware environment includes 4, ESXi 5.1 host servers running 58 virtual machines.
For whatever reason, the previous VMware Admin, did not upgrade VMware and we are now getting ready to do a complete hardware refresh with new physical host and SAN environment.
Since there is no upgrade path from 5.1 to 6.5a, we are going to do a complete new installation of VMware and vCenter.
My question is, will it be possible to migrate our virtual machines from the 5.1 to the new environment or do we have to upgrade the current environment to 5.5 or 6.0 first?
