Upgrade error

Question

Trying to upgrade confluence server to confluence data center and there is an error saying :

Pre-upgrade validation failed. Check the Confluence application logs for more details. You'll need to fix these problems and restart Confluence before you can upgrade.

Upgrade error message: Cannot update schema.

Please help!!!
