People are always ‘a bit twitchy‘ about upgrading their backup software. Mines on my test network so I’m a little more cavalier about diving in and clicking next. So when you want to Upgrade Veeam 10 to Veeam 11, peoples main concerns are;
Will I lose my backup / replication jobs?
Will I need to rescan backup repositories?
Remember Veeam keeps all its data in a database, so your configs should remain unaffected but just to prove it.
Can I Upgrade Veeam 10 to Veeam 11 – Yes
Obviously close any Veeam management windows (in all logged in profiles) before starting.
I always assumed this was either not possible, (without using VMware converter,) or at least very difficult. I downgraded one of my test ESX boxes from 6.5 to 5.5 this week, and needed to lower the hardware versions on some of my VMs accordingly.
Change directory so you are in the right ‘datastore’, locate the VMs folder, and change to that directory. You are looking for the VMs .vmx file, (shown below in green).
Edit the file using ‘vi’ and locate the virtualHW.version value, here it’s version 11 (ESX 6.0).
Here I’m changing it to version 10 (ESX 5.5).
Then remove the VM from the inventory, navigate to its .vmx file and select ‘Register VM‘.

I was seeing intermittent network drops on my Server 2012 R2 servers, so when I took a lot in the logs this was what I found;

Solution
I found plenty of people complaining about this error with servers running Intel physical network cards, but this was a virtual machine? Not only that, but a Windows 2012 R2 Datacenter Machine running on ESXi 6. Forums indicated that it was a problem with the NIC/Driver and that replacing the card had helped. I took a look at the vNIC on the virtual server and was surprised to see it was an E1000 card. This is the default in hardware version 11 for server 2012.
Looking in Windows it’s simply listed at an Intel 82574L Gigabit Network Card.
So I added another network card (a VNXNET 3).
Disable the original card. WARNING: Make sure you are on the console and not remotely connected when you do this!
Give the new card the IP of the old one, and don’t be surprised if you see this popup, CLICK NO.
Then you can remove the original E1000 card.
