I'm trying to upgrade my umbraco 12.0.1 version to Umbraco 12.1.0 and I'm getting this errors when the upgrade wizard is running:
The database failed to upgrade. ERROR: The database configuration failed with the following message: An explicit DROP INDEX is not allowed on index 'umbracoContentVersionCultureVariation.IXumbracoContentVersionCultureVariationVersionId'. It is being used for UNIQUE KEY constraint enforcement. Please check log file for additional information (can be found in 'LoggingSettings.Directory')
Thank you in advance
My issue is the same. What can I clarify to get help here?
I also came across this issue. You can drop these constraints in order for the update to run. The constraints will be added back automatically during the upgrade. Run the following commands against your database:
ALTER TABLE umbracoContentVersionCultureVariation
DROP CONSTRAINT IX_umbracoContentVersionCultureVariation_VersionId
ALTER TABLE umbracoPropertyData
DROP CONSTRAINT IX_umbracoPropertyData_VersionId
