Anytime you upgrade Exchange, there will be some downtime.  You will just have to plan it so it will impact your users minimally.   Weekends, afterhours, etc.

As you have a DAG there will, however be some extra considerations.

Look through this blog.

I know it's a lot of steps, but follow this and things should go smoothly.

This is a great reference that explains the updating process for Exchange in a multi-server environment; and includes DAGs.

FYI... Exchange 2013 CU14 was released on 20 Sep 2016.

No downtime required, if you have DAG in place. Share your design. I will write the steps for you.

You can patch Passive first, then failover to passive site and patch prod server and failback. Have you ever done failover to passive site?

Good, then you can do the patching during off hours or as per your change process. Make sure to take full backup before you start the patching.

Steps:
1) First patch Passive site
2) Failover
3) Patch Primary Site server, which will be in passive mode.
4) Finally, failback and perform all testing. like connecting outlook, OWA, send/rec mails etc.

Also, copy Bin folder at safe location, in case you have any OWA or IIS customization. Take screenshots for any custom setting in advance. Sometimes, it can revert back to default. If no custom setting, then you can ignore it, however I still suggest to do it.
