I have two host that are running esxi 4.0 update 3 and 4.1 update2. I would like to upgrade to 5.1. Do I need to install the patches or will the update bring everything I need?
Thank you
The upgrade should work fine and no manual patches need to be done prior to the upgrade
Below are the best practices
