Today I attempted to migrate from ownCloud 10.0.10 to Nextcloud 12.0.13 following the manual process instructions here:
Unfortunately I received the following error.
# su apache -s /bin/bash -c '/opt/rh/rh-php71/root/bin/php /domains/example.com/occ upgrade' Nextcloud or one of the apps require upgrade - only a limited number of commands are available You may use your browser or the occ upgrade command to do the upgrade Set log level to debug Doctrine\DBAL\Exception\ForeignKeyConstraintViolationException: An exception occurred while executing 'DROP TABLE oc_accounts': SQLSTATE: Integrity constraint violation: 1217 Cannot delete or update a parent row: a foreign key constraint fails Update failed Maintenance mode is kept active Reset log level
I was hoping perhaps someone might be able to point me in the right direction on how to resolve this.
Let me know if any further information is required.
