Started a migration from owncloud 10.0.8 to nextcloud as suggested on Nextcloud - Migration guide
System is debian 9.5, database is postgresql 9.6
Running the web migration and everything went fine.
Did the “occ upgrade” and it fails as already somewhere:
Updating database schema
Doctrine\DBAL\Exception\DriverException: An exception occurred while executing ‘ALTER TABLE oc_filecache ALTER fileid TYPE SERIAL’:SQLSTATE[42704]: Undefined object: 7 ERROR: type "serial" does not exist Update failed
I read here to some psql commands: Update to 11.0.3 failed · Issue #4504 · nextcloud/server · GitHub
but I don’t have even basic knowledge with databases.
So I did:
sudo -i -u postgres psql
and then the failure:
postgres=# ALTER TABLE oc_activity ALTER activity_id TYPE int;
ERROR: relation “oc_activity” does not exist
Any help appreciated. Thanks in advance.
