Migrating OH3 from Linux to Windows: Script Errors, Main UI Black Screen/Won't Load

My first question is - why are so many of the “openhab-cli” commands missing from the “C:\openhab\runtime\bin\client.bat” command-line interface?

openhab-cli is a wrapper around the scripts and bat files you find in runtime/bin. But there really isn’t openhab-cli on a manual install of openHAB and since the only way to install on Windows is a “manual” install (i.e.unzip everything into a folder is the installation).

For many, a move from Linux to Windows would be a step backwards for this and other reasons. You are much more on your own on Windows.

How do I clear the cache?

Clear the Cache

Often when one encounters a problem with OH, particularly after an update, OH will refuse to run or certain parts of OH stop working. Some reported errors include: 500 or 404 errors when accessing the UIs lots of exceptions from Jetty or other core components in openhab.log OH refuses to start at all The first step in debugging the problem is to clear the tmp and cache. Installed OH If you are running an installed OH (openHABian, installed using apt or yum): openhab-cli stop openhab-cl…

@richaardvark

is it at all possible to restore from a backup .zip when migrating from a Linux to Windows openHAB installation?

Yes if it’s not a full backup (i.e. you didn’t supply the --full option). Also, the versions of OH have to be the exact same versions. I’m pretty sure the restore is not smart enough to upgrade/downgrade the configs on the fly.
