Connect the generator transfer switch to a subpanel instead of to the main panel

generatorsubpanel

My house has a generator transfer switch (ProTran 30310B) attached to circuits in the main panel (see photo).

Transfer switch and main panel

I added an attached garage to the house. I want to add a subpanel in the garage, connecting it via 6-3 cable to a 60 amp breaker in the main panel. I will isolate the neutral bar as usual for a subpanel.

Once I do that, can I migrate my transfer switch and the corresponding circuits from the main panel to the subpanel? The goal is to plug my generator in near the subpanel in the garage and to enable some of the new garage circuits to go onto generator power.

You could simply pull a properly sized cable from the transfer switch, out to the garage. Then install a generator input receptacle in the garage.

There's likely a knockout in the bottom of the transfer switch to allow for this. If not, you may be able to add your own (check with the manufacturer).

Moving the transfer switch, and migrating circuits is is likely going to be a huge headache. It's much simpler to pull a single new cable.
