Hi Samuel,

to be honest - i never tried updating the base product itself but i have to try.
i think that it should work if i simply export the product onto the repository.
because of the fact that p2 only updates the IUs required to update, i think 
it's no problem as long as i do not update the system bundle - i have to check 
this also :-)

greetings,
michael
