Hi All- We are soon planning to upgrade the ESXi5.1 to ESXi5.5.
Kindly confirm what all things needs to be taken care, we will be using Update manager.
I know we need to upgrade the VMware tool and VMs hardware version.
Not sure but do we need reboot after upgrading the VMware tool and VMware hardware version of the VMs.
How we can upgrade the data store version?
What is the rollback plan if something goes wrong?
