While attempting to upgrade to DocuWare version 7.4 or higher, you receive the following error; 

"Multiple connections to the Workflow database were found. In order to ensure a successful upgrade, there must be only one connection configured. Please cleanup the Workflow database connections before proceeding."

This occurs when more than one of your database connections has the "Workflow Manager" option selected in the "Used for" section.

Check each database connection and make sure only one has the "Workflow Manager" option selected.
