esxi upgrade

[mario_981]

Hi Everyone ,

We are going to upgrade few of our hosts from 5.1 and 5.5 in steps to 6.5.

We have recently created a new vCenter 6.5 to support the upgraded hosts.

I know we could add 5.5 hosts to 6.5 vCenter, my question is can we upgrade the 5.5 host to 6.5 using 6.5 VCenter Update Manager ? ( or ) I have to manually do using ISO.

Are there any limitations between vCenter Update manager version and esxi upgrade version , please let me know the matrice or link behind it.

Thanks

As long as host verions are supported in vCenter Server, you can upgrade them to the same version as vCenter Server (i.e. 6.5 in your case) using Update Manager.

I assume that you've already made sure that the your hardware supports the new ESXi version.
