Switching openHabian from OH4 32 bit to OH5 64 bit on a Raspberry Pi 4

4

I just want to verify these are the best steps (I’m running Pi4 32 bit, upgrading Pi5 64 bit)

  1. Purchase Pi5

  2. Image Pi5 with OH 5.0

  3. Upgrade my Pi4 32 bit OH 4.3.5 to 4.3.6 to ensure upgrade tool works w/o issues

  4. OH 4.3.6 Backup Pi4 32 bit

Rich’s steps:

  • stop OH 5 on Pi5 64 bit
  • restore your 4.3.6 (backup vs. config)?
  • clear the cache just in case it’s full backup
  • manually run upgradeTool.jar (I think there’s an option in openhab-cli but if not, it’s in OH’s
  • bin folder (/user/share/openhab/bin if I’m remembering correctly)

Frans steps:

  • The openHABian image defaults to timezone Europe/London. If you are not situated in that timezone and change it via openhabian-config, the system timezone wil be changed but not the -Duser.timezone in EXTRA_JAVA_OPTS in /etc/default/openhab, which in my case made my fixed-time rules trigger one hour late. Searching the forum tells me that has been the case for a long time? ( [SOLVED] Log time vs System Time - Mismatch (No Timezone Adjustment) - #4 by BigRedBrent

Did I miss anything?
