VMware App Volumes – Upgrade Manager to v. 2303

Release date: April 7th 2023

Welcome to my VMware App Volumes series. In this session I will describe the steps I took to upgrade my App Volumes Managers. My initial installation of VMware App Volumes was done with v. 2.14. I have since upgraded several times. In this session I will upgrade to v. 2303, which was released on March 30th 2023, version According to VMware’s official documentation, this should be done as step 5 in the supported update sequence, as shown below.

In environments with more than one App Volumes Manager, as I have, I review VMware’s guidelines for Rolling Upgrades before I do the upgrades, available here: Considerations for Performing Rolling Upgrades

Previously, I have shown how to do this manually, but in this session I will do this using PowerShell from my management server. Before I start the upgrade, I verify the installed version

Once done, I start out by downloading the installation media from VMware Customer Connect and open the ISO-file.

Before I start I make myself a little workflow as show below.

First, I create the following credentials to be used in the script:

  • vCenter admin-user:
New-VICredentialStoreItem -User <user> -Password <user> -Host <server> -File C:\<your location.xml>
  • App Volumes Manager admin-user:
$credential = Get-Credential
$credential | Export-CliXml -Path '<path>\appvol_admin.xml'

Now that I have the credentials ready, I am good to go. (PS: I know I’m no programmer and a lot of this script have the potential for improvement, but, it gets the job done, and that’s good enough for me).

Connect-viserver -Server $viserver -User $viuser.user -Password $viuser.password

$avm = "avm fqdn"    # The reason I use fqdn for my VM-name, is that all my vm's are named the same as the fqdn's

#  --- Check for Snapshots and remove any --- 

Get-Snapshot $avm | Remove-Snapshot -confirm:$false

# --- Shut Down VM ---

   $vm = Get-VM -Name $avm -ErrorAction Stop

Remove-PSSession $session

# --- Remove Pre-Upgrade Snapshot ---
Get-VM $avm | Get-snapshot -Name $SnapshotName | Remove-Snapshot  -Confirm:$false

Write-Verbose "Disconnection from vCenter" -Verbose

Once the script finishes I can verify the upgraded version

As I have multiple App Volumes Managers I repeat the procedure above with the other AVM. Once done I check the status in App Volumes Manager Console

Having finished the upgrades, I can now proceed with updating the App Volumes Agent, posted here: VMware App Volumes – Upgrade Agent to v. 2303
