Upgrade from 4 to 6

Hi everyone!

I have been away from the forum for quite a while because my OMV 4 NAS is running flawlessly :). I'm well aware of "never change a running system", but I think it is time that I move to OMV 6. Quick info about my system

230GB Partitioned NVMe boot drive with second partition working as storage drive

3x 8TB WD Red running Snapraid (2x Data, 1x Parity... duh)

Docker plugin with containers like (sonarr, radarr, transmission)

Flashmemory plugin

hd-idle

FTP plugin

Letsencrypt plugin

HomeAssistant running as VM in Virtualbox

Intel i3-8100T

16GB Memory

I'm not trying to find out if all of these services and plugins can run on OMV 6 and whats the best way to get there. Complete fresh install? Upgrading to 5 and then from 5 to 6? Can I backup all the shared folder and users and it's settings as well? How do I backup all the docker container configs? Will Snapraid be able to understand the running config or will it have to start from scratch on the parity drive? Whats the easiest way to backup and restore my boot drive for emergency cases? dd?

Thanks a lot for some input and suggestions!

I would make a clone/image of the OS drive and then try to upgrade from 4 to 5 and then 5 to 6

Upgrade Scripts for non-interactive major release upgrades (2->3, 3->4, 4->5)

EDIT: ATTENTION-Before attempting an upgrade please check if the repo of omv-extras has been updated to github (previously it was on bintray) on your installation:
omv-extras repos moving to github
for OMV4 look at post #9

I recently published some information on how to attempt an upgrade from OMV2 to OMV3 including the upgrade to Debian Jessie. I have now written scripts to automate this process for all three major upgrade paths: 2 to 3, 3 to 4, and 4 to 5.

RE: Is there a guide to in place upgrade?

Contributions wanted:

1. Backup the OS drive (this is allways a good idea, not only for upgrades)
2. Make sure, you have enough free space on your os drive
3. Check any installed plugins if they have been ported to OMV6
   If you are using plugins which have not been / will not be ported, get rid of the plugins except unionfs / mergefolderfs. These two will automatically be be converted to the newer mergerfs plugin
   (Many plugins can be replaced by docker containers. Do this before upgrading)
4. If you installed

Thanks a lot. I have this post already saved in my favourite. I assume I have to move to Portainer for docker, right?

The docker plugin has not been ported. You can use Portainer, Yacht, or just CLI. Up do to you.

If you know the docker plugin, you will find it easy to use the GUI of Portainer.

I prefer to use docker-compose files in Portainer (stacks), though.

Ok I understand, but that means that I need to backup and restore my container configs by hand, correct?

For your own sanity, go for a fresh install.

Most plugins have changed, deprecated or even merged.

And yes, you WILL face issues after the upgrade(s). It's less time consuming to grab existing configurations, do a snapshot just in case and start from scratch.

Somehow this seems to be still the easiest option. What about my data drives? Will OMV see the existing data on it?

I saw that I have an unused nvme laying around. My plan is to replace them and install OMV on this one and keep the current one as my OMV4 backup. Once everything is up and running, the old drive will be wiped and serve as a fast storage on my NAS.

I hope that will make sense and I should be able to go back to my initial config quick easily

Don't worry about your data drives, they can be carried over.

Fresh install is done. Data drives mapped without issues and some basic settings are also applied. The process was actually quite simple, but I still need to all the docker stuff and I saw that there is no more letsencrypt plugin, which is a shame. I guess I have to containerize that as well, right?

Thanks for all the help and feedback. I installed wireguard and it works perfect for my phone, but on my work Laptop I need to switch to the Admin account, to get the UI interface... For that I would like to stick to openvpn. Can someone point me at a recent docker image for that? The one from linuxserver is not maintained anymore...
