Migrating from ownCloud 10.10 and 10.11

[rmelior]

Is your feature request related to a problem? Please describe.
I have a up-to-date ownCloud server (version 10.10) and I want to migrate to nextCloud but I get the message "Exception: Updates between multiple major versions and downgrades are unsupported.". I have tried version 24.0.5 (last) and 20.0.14 of nextCloud with same results.
In "version.php" file OC_VersionCanBeUpgradedFrom indicate migrations can only occurs from owncloud 10.5 .

Describe the solution you'd like
Migrating from ownCloud 10.10 should be possible.

Hello,
I have the same problem with owncloud 10.11.0

Try adding 10.10 or 10.11 here
https://github.com/nextcloud/server/blob/master/version.php#L44

Best on a test/backup instance. Once confirmed working we can more easily go ahead with this.

Since there was barely activity on the database level it might work out pretty fine:

Thanks Joas for having a look! I only found these new migrations in owncloud core:

[nickvergessen]

Yeah

• First one adds an index
• 2+3 do some filesystem stuff but no schema changes, so I'd assume it just works fine like with the old data
• last one adds a config 🤷🏼

[PVince81]

I've tested the following:

1. Download and setup ownCloud 10.11 in "owncloud" folder (needs PHP 7.4)
2. Install "calendar" and "contacts" apps from the market
3. Fill it with a bit of data: files, shares, calendar, contacts
4. Download the Nextcloud 25.0.2rc1 tarball
5. Rename the "owncloud" folder to "owncloud-old"
6. Extract the Nextcloud 25.0.2rc1 tarball into the "owncloud"
7. Delete "config" and "data", and copy the ones from the "owncloud-old" to the new one
8. Create a folder "apps-external" (needed due to it being in the default owncloud config)
9. Edit version.php and add "10.11" in the allowed upgrades
10. Run occ upgrade
11. Reinstall calendar and contact apps: occ app:enable calendar and occ app:enable contacts
12. Test in the web UI and check that the data is still there

=> the upgrade went fine!

So the only extra steps one needs to do right now is:

• create a "apps-external" folder, or alternatively remove it from config.php
• edit version.php and add "10.11" as allowed upgrade

for version.php I think this is something we can do officially in a PR.
for the "apps-external" folder it would need to be mentioned in the upgrade documentation

@Rico29 I didn't see such errors.

I've checked the data directory after the upgrade and I can see that the theming folder exists:

68 directories, 43 files

maybe you can check your app data folder before and after the upgrade ?

[Rico29]

thanks for the quick response.
My bad, I did not see that appadata folder was in data storage. My data folder is elsewhere that in owncloud root directory. I chowned it and I don't have the problem anymore.
Sorry for my mistake, everything seems to work as expected now
Regards

[AndyScherzinger]

Thanks a million for the feedback and testing @Rico29 - highly appreciate this 💙

Have fun with your migrated Nextcloud instance 🎉

[Rico29]

I still have a warning about file integrity for file version.php which has been modified to add "10.11" in the allowed upgrades
any way to ack new checksum / force OK ? or should I remove "10.11" in version.php file ?
Regards

[PVince81]

@Rico29 you can ignore this for now. Once you upgrade to 25.0.2 final later on the warning will disappear because the change there will be official

[szaimen]

Closing as the backport is merged

Welcome to Nextcloud @Rico29 I hope you'll have a good experience!
