Upgrade ESXi and vcenter

Hi Experts,

I have vSphere running, version 5.5
Now I want to upgrade to the latest version 6.x

Am I right to upgrade first the vcenter ?

Later on I upgrade host by host with my update Manager, is it possible like this ?
Or what do you recommend ?

Absolutely yes, because you got to !

Yes if you have VMware Update Manager installed and working, this is your best way to do it nicely.
Just migrate VM on other hosts and put your host-to-be-upgraded in maintenance mode.

Personnally I would rather reinstall my hosts than upgrade them, but I may be wrong, lets see what other experts have to say about it  :-)

Hi all,
thanks for the help and recommendations.

Since now I will not use the appliance, because of VUM.
When I upgrade my vcenter, shall I upgrade or uninstall and install again ?
Mr TorturSystem EngineerCommented:
Hi,
IMHO you should reinstall, but you can upgrade if you need to keep some objects (e.g. saved customization of vm deployed from template) and past vcenter statistics.
Or take the chance to migrate from Windows vCenter to the vCSA appliance!
Andrew Hancock (VMware vExpert / EE MVE^2)VMware and Virtualization ConsultantCommented:
Upgrade if it works, sometimes upgrades break.

Make sure you have a full backup or CLONE before you start, not a snapshot.

Migration from vCenter Server to VCSA appliance is not supported for production at present.

I was meaning do a fresh install of vCSA instead of keeping a Windows vCenter.

ok I will wait for vCSA until the VUM is included.
