Mixing ESXi 6.5 build versions in HA/DRS cluster


I’m planning on updating my ESX6.5U1 hosts to latest build of ESXi6.5U3. Is there any considerations for how long the hosts can be mixed versions in the cluster during update phase? I was thinking about doing it over a week or two.

I would appreciate any advice if this sounds ok or if there is any considerations for the HA/DRS cluster?

  1. Should not be a problem. For safety test a Vmotion to and from the updated server. Also test it with a guest that has had a power on on the updated host.
