During upgrade of Change Auditor Coordinator the following error may occur:
"Warning! A database with this name exists but it is not compatible with current version of a product. If you would like to create a new database, then you should provide a different name. User the same name will permanently overwrite the existing database. Uninstall will not restore the database. If you are not certain, please contact Support."
Ensure the user specified in the Change Auditor database connection string has DBO permission on the Change Auditor database.
Defect TF00592013 has been logged to resolve the misleading error in a future release.
