Upgrading Windows Server 2016 to 2022 via Remote Desktop Connection

lc flag

I need to perform an in-place upgrade of a remotely located Windows 2016 server to 2022 (or 2019). My only access to it is via Remote Desktop connection. Knowing that the upgrade process may require restarts, will I be able to re-connect my remote desktop session to continue with the upgrade process?

Obviously I need to know before attempting. I don't want to get into a situation where I can no longer connect to the server after a restart and have to get someone on site to finish it up.

Without a real remote *console* capability, you are on a real mission to shoot yourself in the foot. Leaving aside the whole problem that in-place upgrade is a bad idea anyway. Without any idea of the infrastructure, it's hard to make suggestions. If it's a physical computer in a branch office cupboard, get someone to buy replacement hardware - with remote management like DRAC/iLO this time - install the new OS, preload the data/app/whatever, get someone to pay to install the new box in the remote location and finalise data migration.

Thank you for your comments. Believe me, I wish I could do it the right/safe way, but it is just not possible. However, in order to preserve my foot, I will at least make sure the gun is not loaded. :-)

All I can really advise now is to make sure any paperwork outlines the risk that this could a) corrupt the OS or application, or b) make the system unserviceable remotely - and ensure that someone in change control or management has reviewed and acknowledged those risks IN WRITING. It will *likely* work in terms of the OS upgrade, at least, and remain connected. But the risk is not nothing. (To be really frank, I'd start looking for a better job, with better resources and risk-management (I get it, beggars can't be choosers, but no harm looking :-) ))

If everything goes smooth, you will not loose RDP access. However, there is simply no 100% way to know this for sure in advance. There are countless scenarios how in-place upgrade can fail, so you definitely need to prepare a recovery plan in case remote upgrade goes wrong.

Anyway, general Microsoft recommendations can be found here: https://learn.microsoft.com/en-us/windows-server/get-started/perform-in-place-upgrade

Thank you for your reply. I was more concerned as to whether the RDP settings were reset, changed or in any way touched during the upgrade. Obviously, failures, errors and such is a whole nuther ball game. Much appreciated...

RDP settings should stay, unless stated otherwise in upgrade documentation

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
