Migration from Owncloud 9.1.6 to Nextcloud 10.0.5 fails

Hi @Morgano please report this on the appropriate issue tracker https://github.com/nextcloud/nextcloud.com :wink:

Instruction: https://github.com/nextcloud/server/issues/5426 (first issued as https://github.com/nextcloud/nextcloud.com/issues/496 )
Script: https://github.com/nextcloud/server/issues/5425 (first issued as https://github.com/nextcloud/nextcloud.com/issues/497 )

@Morgano thanks for filing the issues. The Nextcloud updater should ignore minor versions (the .5 vs .6) on migration between different products (oC to Nc), but apparently something is wrong. It might be that oC didn’t properly set the vendor on install or update, there was a bug with that. Once 10.0.6 is out it should of course work but this isn’t nice so we have to look if we can work around it…

A work-around from this blog is to set the version of your ownCloud server to, see:

edit your config/config.php and set version to or lower.

From @nickvergessen - if the reason is that oC didn’t set the vendor properly, you should run this before you try to upgrade to Nextcloud:

occ config:app:set --value "owncloud" core vendor

Reading from posts earlier in this thread, and other places, I am told that OC 9.1.6 use a newer engine than OC 9.1.5 and NC 10.0.5, so that is not a safe path anyhow. Or is there news on that?

It do seem to work for some anyhow, but i am trying to define an official upgrade path for Mageia 5 (owncloud) to Mageia 6 (nextcloud) that is doable ASAP. https://bugs.mageia.org/show_bug.cgi?id=20953#c21 , https://wiki.mageia.org/en/OwnCloud#IMPORTANT_:.2ABEFORE.2A_upgrading_to_Mageia_6.21

It there any idea yet when NC 10.0.6 (or other compatible NC) is out: like in a week, or four weeks?
If soon, maybe we can get NC 10.0.6 into Mageia5 backports

I agree with the assesment from the blog on https://0xstubs.org/migrating-from-owncloud-9-1-6-to-nextcloud-10/ that there don’t seem to be any changes to the database, which would indeed be unlikely in such a late-in-the-series bugfix. This should not cause any problems.

However, I’m testing this myself now with a fresh 9.1.6 and will try to fix this out. Will get back to you all.

Many thanks :slight_smile:
If the workaround is safe, it will save a lot of people some work.

In my case, I had to set version in file version.php. When I set config/config.php, the updater still recognize installed owncloud version as 9.1.6.

In the end, migration from owncloud 9.1.6 (faking it as a version) to nextcloud 10 to nextcloud 11 went well.

FYI - https://github.com/nextcloud/owncloud-web-migrator/issues/1

I modified version.php to refer to which worked for me but didn’t work for a user on twitter. We have to fix the migration script… The upgrade itself, if you manually replace the files that is, does work.

Thanks, jospoortvliet
I see you fixed the migration information :smiley:

Still broke btw…

The updater script issue https://github.com/nextcloud/server/issues/5425 got closed now with “There is a patch in the repo for this already.”

The documentation issue https://github.com/nextcloud/server/issues/5426 erroneoulsy got closed as a duplicate of above, while it should be closed fixed, as i now see at https://nextcloud.com/migration/ :

Note that ownCloud 9.1.6 breaks easy upgrading to Nextcloud 10.0.5. We will fix this in 10.0.6! Similar, ownCloud 10.0.2 and 10.0.3 can’t yet be upgraded to Nextcloud 12, which will be fixed with Nextcloud 12.0.1. We want to make sure we properly test the upgrade paths!

As always there may be further issues too… Just run into this theming bug https://github.com/nextcloud/server/issues/4987 on 11 something to 12.0.0 upgrade

Nextcloud 10.0.6 is available since August 7th. But:

What’s the status then?

seems like the update server tells the migration script what to do:

url from updater log: https://updates.nextcloud.org/owncloud-migration/?version=9x1x6x2xxxstablexx2017-05-30T17%3A13%3A25%2B00%3A00+0e399c6378c925c6859b4412dd142a862db1544ex5x6x30


<?xml version="1.0" encoding="UTF-8"?>
 <versionstring>Nextcloud 10.0.5</versionstring>

Any update? Migration is still broke.

Migration tool report

Current version is 9.1.6.
Migration to Nextcloud 10.0.5 available.
Following file will be downloaded automatically: https://download.nextcloud.com/server/releases/nextcloud-10.0.5.zip

Can’t continue migration … Nextcloud 10.0.6 is needed during migration … and is available for download
Nobody there to correct the migration process … ???

Hello all,

I’ve hit the same wall a few weeks ago and I found a workaround that worked for me: perhaps can help someone.

I downloaded the owncloud-10.0.0 tarball from owncloud and used it to upgrade my former owncloud installation. After that the nextcloud upgrade to 12.0.0 worked like a charm… :slight_smile:

I’m in discussion about this subject on Github:
