We have all hosts in a given cluster running the same build of ESXi. 6.5p02 build 7327119. The VM tools version associated with this ESXi build is VM Tools build 10287.
The problem we are seeing is that if a VM lives on host A, and is running VM Tools 10279, vcenter indicates it is the current build of tools. If that VM is migrated to host B, vCenter indicates the tools can be upgraded and doing so, upgrades it to 10287. Both Host A and Host B are running the same exact builds of ESXi and have all the same patches applied.
Same with a brand new VM or a VM running an older pre 6.5 version of tools. If you install/upgrade tools while the VM is on Host A, it gets Tools version 10279. If you install/upgrade while on Host B it gets Tools Version 10287.
What is happening here?
