Upgrade 4.1.23-1 (Arrakis) to omv 6

The road is long and you will probably encounter some difficulty.

OMV4 to OMV5 upgrade

Check that everything is ok (potentially solve problems).

OMV5 to OMV6

Check that everything is ok (potentially solve problems)

If you have OMV on a separate drive I would unplug the data drive and do a fresh install. Then mount the data disk, you will not lose the data.

OMV4 to 5 is rough. There are update scripts

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.

OMV5 to 6 is much smoother. You basically can run omv-release-upgrade after removing all plugins that have not been ported to OMV6.

As chente suggest, a fresh install might be the route to take

Thanks macom , I couldn't find that link to upgrade from 4 to 5.

andrewgbailey , a couple more things.

If you decide to update, in step 5 to 6 remember to remove the plugins that have not been ported to OMV6, here is the list. omv-extras plugins - porting progress to OMV 6.x (done)

If you decide to do a fresh install, when you mount the data disk DO NOT format it, just mount it in the OMV interface.
