If we enable DMC in Search head in a Production environment is there any impact on the searches.

I have a lot of historical searches are running on it.
Is it the Best practice to do?

Just enabling it will not cause any problems BUT, if you fully configure it and add non-indexers as search peers (which you have to do to get the full features/data), you will be creating potential search results data duplication, search delays, incorrect warnings and errors reported in the UI and other minor problems. None of these are serious, but it is still a poor practice.

click settingdg dropdown -> general settings -> on the top line (your DMC instance name) on the right hand side click edit -> disable. notice it says "disabled" with a little red X
Do not click "Apply All Changes" afterwards

best will be to have a dedicated Search Head for the DMC (now MC)
