Old Galvanized shower/bath inlets Relpace Pex?

The Shower bath is nothing fancy, just two knobs Hot-cold and a knob that switches to shower-bath function.
I have to replace very old galvanized inlet water pipes to the shower/bath, with pex pipe.
It looks like the old galvanized pipes are threaded into the fixture(s) hot/cold that look like brass that have a nut at the very top and taper to where the galvanized pipe is threaded in.
Im hoping to use adaptor 'Flare-it' 1/2 x 1/2 that will hopfully thread into the inlets...
Question, do I have to cut the galvanized pipe to loosen it from the brass fitting?
Will a regular pipe cutter do the job?
What if the brass and galvanized metal have seized, how can they be loosened?
Thank You!

If your shower is old enough to be plumbed with galv., I think it is time to spring for a new valve along with the PEX re-plumb.

Valve Replacement?

Thank You for Your Reply!

If I got a new valve thing ( I think your talking about all those other little pipe things; with one that runs up to the shower). Then all I would have to do is cut the inlet galvanized lines?

Ive read other posts where I think they are talking about the "valve tjhing" sweating fixutes; would I have to do that too??
