I suggest that you provide which version of MySQL 5.X certified to be used as external database as the document only mentions MySQL 5.X
In the Docuware document, there is only reference says MySQL 5.X is supported for external database. But MySQL has been evolving in every major version and some features might be expired/unavailable anymore in newer version. Thus this makes it difficult for end users to confidently decide to use existing MySQL 5.6 or 5.7 for Docuware index store. Any idea if MySQL 5.6 or 5.7 supported to be external database by Docuware?
You can find the system requirements for version 6.10 (stating to support MySQL 5.7) here: http://help.docuware.com/en/#b57865t62677n70156
