Upgrading to Veeam Backup & Replication v12, build 12.1

I previously shared my experience when I installed Veeam Backup & Replication v12, build

v12.1 received a lot of attention during the Veeam 100 Summit, and I highly suggest you review the content that was shared here, but also check out the links found at the bottom of that post from fellow Veeam Vanguards!

It’s now time to upgrade to build 12.1 (the image below is from my current Veeam Backup & Replication Server):

Once the ISO has been downloaded, you’ll then need to mount it. As my good friend Nico Stein mentioned in his blog post linked at the bottom of this post, it’s always a good practice to capture a backup of your Veeam config first, and also ensure no backup jobs are running before you begin with the upgrade.
