Hey guys, I just inherited an older 6.0 cluster and the tools and hardware versions are pretty old(mostly VM versions 7,8,& 11). I have a new 6.5 cluster and have migrated most of the VMs across and need to get the tools updated first, and thinking it would also be good to get some of the hardware updated at the same time. It sounds like VMWare does not recommend upgrading you hardware, unless there is a reason. My backup solution(Rubrik) does not officially support restoring a VM unless it is hardware level 8. So I am thinking, I at least need to get there for all VMs, but have a few questions. 1. If I tell all my VMs(servers)to install Tools(automatic) and hold for reboot(with the various command switches) and leave them all pending, will that cause any issues with dropped network(when nic driver updates, etc)? Has anyone ever done that against 100+ servers? 2. Should I go after trying to get all my VM versions updated all the way, or not? (I know I could take snapshots and failback) The other option is to follow VMWare's advice and leave them alone? 3. If I do tell a server to upgrade tools(automatic), and hold the reboot(with the advanced option command) . Then I power it off, upgrade hardware version, and power it back on all in the same reboot. Is that an issue? Thanks,
↧
