Migration question

Setup, Configuration and Use Migration
#1

I currently have OH 2.5 (OpenHabian) on my pi. I’d like to wipe out 2.5 do a complete fresh 3.0 install. I have never tried to do a clean install since I used an OpenHabian card image, and then just the automated updates ever since. I do not see any instructions anywhere to for how to do a clean install of OH3-RC1. The instructions for snapshots and milestones are for different repositories.

It seems like there must be more to it than just this:

sudo apt purge openhab2
sudo apt update
sudo apt install openhab

This should give you a good starting point
Guide: Installing and testing OH3 snapshots/milestones using APT and YUM

Yes I’m there. The very bottom about using other versions seems to apply.

wget https://openhab.jfrog.io/openhab/list/openhab-linuxpkg/pool/main/3.0.0~S1919/openhab_3.0.0~S1919-1_all.deb
sudo apt install ./openhab_3.0.0~S1919-1_all.deb

But in the RC1 directory, there are 4 different files to choose from.

openhab-addons_3.0.0~RC1-1_all.deb   14-Dec-2020 16:00  164.68 MB
openhab-addons_3.0.0~RC1-2_all.deb   14-Dec-2020 22:02  164.68 MB
openhab_3.0.0~RC1-1_all.deb          14-Dec-2020 16:00  79.18 MB
openhab_3.0.0~RC1-2_all.deb          14-Dec-2020 22:02  79.18 MB

So which one am I supposed to use?

How will this impact things like Grafana and InfluxDB? I’m guessing since those are separately installed applications, they will need to be reconfigured from scratch?

#5

Can’t answer this reliably as I don’t use them in my current test-environment - but I can tell that there is a nice standard graphing tool based on rrd4j persistence already integrated, which should suit the most common needs.

#6

Cool. I will pull the trigger after work tomorrow. I wish I had a spare pi to install this on so I could experiment without nuking the operational unit.

#7

You should be able to just use a second sd card with a new image.

#8

I’d start with a fresh new SD Card and use openHABian, which provides already a openHAB3 (milestone or build) option with sudo openhabian-config.
then do as described as above.
and then here

I myself switch from textfile-based configuration (OH2) to UI-based configuration (OH3) and therefore don’t migrate something, but built anew from scratch, also to get rid of some old f$%ked up namespacing of items and stuff and I move to the new Model-based approach, which I really like…

so basically I already started a few weeks back with the milestones and learned by doing. OK, I do have a whole bunch of Pis to do my tests, and my “old” OH2 still runs as main instance and will until I finally pull the switch to OH3…

#9

Actually the newest milestone is Release Candidate 1. I would be sure to read up on it first though. It has been out less than 24 hours and there may be bugs in it.

#10

there are a few, if I follow correctly, but presently I just built my model and integrate all bindings I can use in parallel, and if noone tests the RC, the bugs cannot be found and fixed! :wink:

#11

True, but Milestone 4 was such a disaster I am just a little extra hesitant.

I read this and spent the next several minutes staring at the screen wondering why on earth I didn’t think of that…

Well that got as far as step two before the first failure.

[03:41:56] openhabian@openHABianDevice:~$ sudo openhabian-config
[sudo] password for openhabian:
openhabian is not in the sudoers file.  This incident will be reported.
[03:43:05] openhabian@openHABianDevice:~$

Unless there is some other user with rights, I assume I will need start over reburning the SD card?

Update: Burned image and redid install, same problem. Dead stop at step one since there is no way past this I can see.
