Hey guys - thanks for all the advise. I finally got around to updating my system and bought a separate SD card just in case. The only issue I had was enabling SMB (which I was unable to do because of the browser, switched the browser and I was able to enable SMB).
It just worked - I had recorded all the settings (using my phone) and just set everything up that way it was. Works fine. I'll keep the other sd card as a backup just in case something gets funky!
