Ok ;-) that depends on the code in your php. If you just add two db 
fields, there should be no problem. You can test an upgrade locally.
Go to extensionmanager, select your extension then "backup/delete" and 
download an .t3x file of your new extension. Reinstall your original and 
test an upgrade with that .t3x (delete your tx tables before install old 
one)
normally not a problem.
