Upgrading Windows OS where PRTG is installed

We currently have a root server and multiple probe servers running on Windows Server 2008 R2 virtual machines. Because Server 2008 R2 is approaching End of Life, we want to upgrade these servers to Server 2012 R2 or Server 2016 by upgrading the OS in-place. This is as opposed to building a new server and moving PRTG to it (for several reasons we only want to do that as a last resort).

Are there any caveats or things we should be aware of regarding PRTG before we perform the OS upgrade? For the sake of our sanity, we would like this process to complete as smoothly as possible.

Thank you in advance!

Hello,

What version of PRTG are you currently running?

Here's what I would do. If you are running 18.2.40, then I would do the upgrade and see how it goes. We are planning to release a new stable version in early June that you can update to if the installation isn't very reliable.

Or, you can download the latest version of PRTG fromhere.

Use that to re-install a clean version of PRTG.

If you have any other questions, let us know.

Thanks!

Sorry about not including the version -- we have 18.1.38.11958 currently. Should we update that to the latest 18.2 before attempting the OS update?

Pete,

No that's perfect! Do the upgrade of PRTG after you upgrade the OS. The PRTG upgrade should correct any problems that would have come from the OS upgrade.

Thanks!

I have a follow-up question on this. We have three probe servers that report to the root PRTG server. Do we need to upgrade the OS on all of these first before upgrading PRTG on the root server (after its OS has been updated to 2012)?

The OS doesn't matter for PRTG in this case. Like, OS of the Core and the Probe(s) don't have to match.


Kind regards,

Hi,

we've some Remote Probes on VM with Windows Server 2008 R2. what is the easiest and safest way to upgrade without losing the logs and statistics?

New VM with new OS and Drag & Drop the Devices to the new VM? Or another way? What is your Experience?

Thanks and Greetings.

Hi Michel,

Exactly that. New VM, set up the remote probe and then move everything to the new probe. Make sure the probe either has the same IP or hostname, depending on the SNMP configuration. If different Windows credentials are required [different from the root node], configure them as well.
