There is one thing to watch out for, the white wires.
The AC common wire is white
The DC negative wire is white on most of the circuits coming back from the devices.
Make sure you keep track of which is which. Take pictures, and mark them if needed before you take them off the terminal strip. You do not want to put the DC neg white wire onto the AC common terminal strip. Or visa verses. Doing so will upset the grounding system and trip most any GFIC wall outlet you ever plug into. Plus is has some saftey concerns mixing them up by accident.
On the breakers, unless they have been abused and are not cracked or damaged you can see right now, I would reuse them as long as they fit nice and tight in the new convertor. Good breakers have lasted a long time.
Look for black marks on the screw terminal of the breakers, sometimes these get loose from towing down the road and may arc when powered up. It still may be OK but be on the lookout as that one may have been abused this way and have issues some time down the road.
Hope this helps and good luck.
