No need to do anything with MCC and I  suggest you don't, changing roles 
is likely to break things!

Assuming you are using Ubuntu based distribution with systemd e.g. 
mythbuntu 16.04 you can control mythbackend startup as follows:

1. To stop mythbackend running at boot

sudo systemctl stop mythtv-backend
sudo systemctl disable mythtv-backend

2. To enable mythbackend at boot

sudo systemctl enable mythtv-backend
sudo systemctl start mythtv-backend

Note: systemctl automatically looks for the .service extension, so no 
need to type it.

You can check if mythbackend is running using either:

ps -A | grep mythbackend

or systemctl status mythtv-backend


You will need to adjust the ~/.mythtv.config.xml file to suit each of 
your backends

What I do is setup two config.xml files :
one named local-config.xml, the other named remote-config.xml (each with 
appropriate contents) and overwrite config.xml with whichever one I want 
to use in ~/.mythtv/

e.g. change to directory cd ~/.mythtv
cp local-config.xml config.xml
