Bolt install

Need some advice if available.

Here is my current setup:

1 Roamio with 4 Mini's

Comcast is my provider - Not X1

I bought a Bolt and want to add the Bolt to one of the rooms where a Mini currently resides. Take that Mini and put it where the Roamio is.

I haven't attempted anything yet - it's been 2 years since the original install and that took me 3 days to get all dialed in.

Any advice or links to the process is greatly appreciated.
