Hello everyone. I installed Confluence 6.9 and I want to use data from database (with Confluence 5.7). But I have several problems. For example Upgrade failed. Please consult the system logs for details. You will need to fix these problems, restore your database and confluence home directory to the pre upgrade state. Then retry the upgrade. Upgrade error message: Upgrade task com.atlassian.confluence.upgrade.upgradetask.DropSpaceGroupTablesUpgradeTask@f4c95ed failed during the SCHEMA_UPGRADE phase due to: nullI've found the following solution : https://confluence.atlassian.com/confkb/upgrading-to-confluence-5-9-x-or-5-10-x-fails-with-error-failed-during-the-schema_upgrade-phase-due-to-null-794212749.htmlBut It's not working: Key column 'SPACEGROUPID' doesn't exist in table How to fix It?)
Andrew,
Can you let us know the exact steps you took to upgrade Confluence? Please also confirm your database version.
Thank you!
Shannon
