It's good that you asked first. Yes you will be overwriting existing patches. You should do a bulk sysex dump to your PC and make sure it is good before you start experimenting with new sounds. See if you can send it back again from the PC to the synth OK. That way whatever happens you can always go back to what you have now. Most MIDI sequencers have sysex support and there are some freeware utilities out there as well.

Now if there are some particular patches you want in the the new setup you may need to do a sysex dump of individual voices so you can bring some of them back later without bringing them all. Or vice versa when you load the new sounds you may just want a few of them to load into your standard setup.
