Sorry if I ask a common question, I couldn't find anything with a cursory google.
My question is: is it legal RAW to have a crafter upgrade, for example, a Belt of Mighty Constitution +2 into a Belt of Physical Might/Perfection +2?
As far as I see it, it should be ok, as you would still have access to the spells needed for the original item, and would use the original item as part of the material cost for the newer item.
For regular rules, yes it'll be fine. Just pay the difference.
