    How critical is VMware tools upgrade?

    taylorb Expert

      Just did a big ESX 4 to ESXi 4.1 upgrade this weekend and now it says all my VMs have out of date VM tools.   I tried upgrading a few and it reboots during the upgrade.  These are about 60 production VMs, so I can't do that unless I specifically schedule downtime which may be another month.   I guess I am wondering if it is a big deal to leave the tools at the older version and if it will negatively impact anything.
