Hi Markus,
let me jump in here and ask a specific question on migrating from OH2 on RP3 to OH3 on RP4 which I intend to do.
I read the section “On Openhab 3” carefully at your openhabian documentation.
Can you verify if this is the right way to go?
- Take a config backup on the RP3 with OH2 (with openhab-cli tool )
- Install a fresh openhabian on the RP4
- Downgrade to OH2 on the RP4 (Menu option 42)
- Restore the config backup
4a) check if OH2 is running ? - Upgrade to OH3
Would this be your recommendation?
