Migrating vom Owncloud to Nextcloud failed

Migrating from Owncloud 10.0.7.2 to Nextcloud 12.0.4 with migrating scrip failed.

Nextcloud version (eg, 12.0.2): 12,0.4
Operating system and version (eg, Ubuntu 17.04): Ubuntu 16.04
Apache or nginx version (eg, Apache 2.4.25): 2.4.18
PHP version (eg, 7.1): 7.0.28

The issue you are facing:

Migration from Owncloud 10.0.7.2 to Netxcloud 12.0.4 failed

Is this the first time you’ve seen this error? (Y/N): Y

Steps to replicate it:

  1. I downloaded migration script from https://nextcloud.com/migration/
  2. Ran script - download succeeded
  3. Upgrade process stopped then with “Exception: Updates between multiple major versions and downgrades are unsupported.”

Any help?

I could solve it.

The migrate script seems to be broken - it downloads version 12.0.4 - and with this version it isn’t possible to migrate.

I manually downloaded version 12.0.6 - and migration finished yet.
