*Hello everyone
I would like to update my version of OH 2.1 on windows at 2.2 and then 2.3, if it works without problems.
I tried the procedure with the powershell script, but it gave me a lot of errors. Luckily I had backed up the folder before, and I managed to restore version 2.1
I decided to try to follow this procedure:
https://docs.openhab.org/installation/windows.html
but I can not find the 2.2 version to download, I only find the latest release, also what is the difference between “distro” “snapshot” and “release”?
Thanks for your help
Davide
From the docs
Then, you can choose between, Official (Stable), Beta or Snapshot builds:
Stable Release
The stable builds contain the latest official release with tested features.
Add the openHAB 2 Stable Repository to your systems apt sources list:
echo 'deb https://dl.bintray.com/openhab/apt-repo2 stable main' | sudo tee /etc/apt/sources.list.d/openhab2.list
Testing Release
The beta and release candidate builds come out less frequently, but will contain new features that are currently in the testing phase.
Add the openHAB 2 Beta Repository to your systems apt sources list:
echo 'deb https://dl.bintray.com/openhab/apt-repo2 testing main' | sudo tee /etc/apt/sources.list.d/openhab2.list
Snapshot Release
The snapshot build is created almost daily, and include the latest changes to the openHAB 2 core and add-ons. These changes are often unstable, so you should use this branch only for testing or development purposes.
That’s for linux but the definitions of the releases remain the same.
We are now on 2.3 so you can upgrade directly to 2.3
I do not use windows so I can’t help you futher here, sorry
I was able to upgrade using the manual procedure.
I say this for the windows users, since we are few 
In the procedure it says not to overwrite the files when requested, but to me it only worked by overwriting them. I do not know if it is an error in the description of the procedure or I was lucky.
However, everything seems to work fine, all the bindings installed except for Gcal, which drives me crazy all day.
I’ll do some tests in the next few days.
I thank Vincent Regaud for the explanation
David
it does not work gcal, I tried to uninstall the bindings and do a clean new install, but it does not work.
Also from the log I see many errors
But is it possible that there is no way for windows to upgrade without errors?
