Can you use Crafting to upgrade an item you originally purchased?

[Fyn N' Gyn]

Example: I buy a wand of Mage Armor (1st level); it's a level 3 item and costs 60 gp. Later, I want a wand of Mage Armor (4th level); it's a level 9 item and costs 700 gp.

Can I A) Craft the second wand as an upgrade from the 1st (in which case the base cost is 640 gp - I have to pay half of that as usual, and then can Craft to attempt to reduce the cost)?

Or do I B) have to sell my first wand (for 30 gp) and then Craft the second one from scratch?

There is nothing I am aware of that prevents you from using crafting to upgrade a wand you initially purchased.

You probably already know all the other things you need too, but just a helpful reminder.

You must be at least level 9 to craft it and you must be a master in crafting.

You must have the formula.

You must have cash equal to half the value (320gp in this case)

Yep, many thanks!
