SQL Server Updates

What are your thoughts on applying a cumulative update for our DocuWare SQL server 2017? It is labeled as a Hotfix, but not sure if by applying it would affect Docuware performance or affect the integrity between the DocuWare server and and the SQL server. We are running DocuWare ver 7.8. which was recently upgraded last year, on Windows Server 2019.
 

Hello David Blake, 

you should always keep your SQL Servers up to date, this also applies to the DocuWare SQL Servers.
However, you should stop the DocuWare Services before applying the SQL Server Update.
