Guide for upgrading Vsphere 4.1 to 5.5?

Does anyone have an easy to follow guide for upgrading Vsphere 4.1 to 5.5 using update manager (or another method)?

Here is my environment.

Vsphere 4.1 (260247) on 3 hosts.

Vcenter 4 on a virtual host.

Update Manager installed on Vcenter.

Thanks for any suggestions!

Hi Friend,

- Upgrade your vCenter to 5.5 or install a new one so you can manage your ESX 4.1 hosts
- Use the update manager to upgrade your first host 4.1 to 5.5
- Attach the  all other 4.1 and newly upgraded 5.5 ESX to the vCenter
- Ensure the external Storage is visible to both 4.1 and 5.5
- Migrate your VMs from other 4.1 host to new 5.5 host with Storage VMotion
- Upgrade VMware tools on the VMs

Hello,

I leave you with 2 KB procedures:

Upgrade vCenter:

VMware KB: Upgrading to vCenter Server 5.5 best practices

Upgrade Esxi:

VMware KB: Methods for upgrading to ESXi 5.5

Points to consider:

1 - IMPORTANT: Before doing the upgrade of the VC you must make a full backup of the DB.

2 - IMPORTANT: If the VC is virtual, must make a clone.

3 - The upgrade of ESXi is very easy, you do it through the VUM.

For ESXi I recommend you to go download the ISOs customized manufacturers.

PLEASE CONSIDER AWARDING any HELPFUL or CORRECT answer. Thanks!!
Por favor CONSIDERA PREMIAR cualquier respuesta ÚTIL o CORRECTA. ¡¡Muchas gracias!!

Thanks for those simple steps!

  1. So before I upgrade my Vcenter to 5.5 I suppose I should make a snapshot of it or clone it (Just in-case the upgrade doesn't go well)?
  2. If 1 host is upgraded to 5.5 and one is at 4.1 will vmotion'ing vm's still work?  I wanna make sure the upgraded 5.5 host works and the VM's on it run before I upgrade the rest of the hosts.

Thanks again so much.

vMotion will still work as long as you have the correct EVC mode set (if needed).

I recently upgraded an environment from 4.1 to 5.5 and I created a completely new vCenter on a fresh host. I then disconnected the other hosts from the 4.1 vCenter and added them to the 5.5. I like to start fresh (especially when going from 4.1 to 5.5) if you don't need all the statistical data from the old 4.1 vCenter.

Just my .02

1. As described in below docs, you should backup your vCenter prior upgrade.

VMware KB: Upgrading to vCenter Server 5.5 best practices

vSphere 5.5 Documentation Center - Best Practices for vCenter Server Upgrades

2. You can vMotion from 4.1 host to new 5.5 hosts as long as they have same CPU Series, the procedures are described here: vSphere 5.5 Documentation Center - Moving Virtual Machines Using vMotion During an Upgrade

Use this to check the CPU Series/Matrix:http://www.vmware.com/resources/compatibility/search.php?deviceCategory=cpu

If they are belong to different CPU Series, you can only perform Cold Migration (requires downtime) or enable EVC as described by ClintColding in above post.

vSphere 5.5 Documentation Center - Virtual Machine Migration

Cold migration: Moves a powered-off virtual machine to a new host. Optionally, you can relocate configuration and disk files to new storage locations. Cold migration can be used to migrate virtual machines from one datacenter to another.

Does anyone know if I need to patch my ESXi HOSTS to a certain patch level before I upgrade vCenter?  I'm at 4.1 260247 (so really no updates/patches at all).  Update manager says I have 35 patches.  I'm not sure I need to install them first before I upgrade my vCenter to 5.5.
