Migrating from ownCloud 10.5.0 to NextCloud 12.0.12

Hi guys !
I’m trying to migrate from ownCloud 10.5.0 to NextCloud 12.0.12 using the migration tool but I get error due to extra files:
* ## Check for expected files

The following extra files have been found:
* .htrnwby8ugdxte.data
* ocm-provider

And the .htrnwby8ugdxte.data folder seems to be the folder that contains all the actual files on the cloud. Is that normal ? Will it break anything if I simply add those folders to the “getExpectedElementsList” function in the updater ?

Thanks in advance for your help :slight_smile:

Any ideas ? Has anyone migrated from ownCloud 10.5 to NextCloud 12.0.12 ?

Sorry i can not really help you. i think the problem is, that Nextcloud 12 is also a very old version. After migration from Owncloud to Nextcloud you must upgrade from Nextcloud 12 to Nextcloud 19 and you can not leave any version. I think it breaks again.

Perhaps you can better install a new Nextcloud 19, create new users, copy all data from Owncloud to Nextcloud and rescan all. The problem is you lost all other data like the shares, calender, … Is this an option for you?
