Here is what is meant by armor upgrading.
"Rogue's armor: no longer provides less Energy than standard armor."
New Canthan Rogue's armor has no energy penalty, yet old Rogue's armor(crafted in Tyria) still has the energy penalty. So...
"New armor designs from Cantha have begun to influence armor crafters in Tyria. Existing armor sets will not be updated yet, but a means to upgrade existing level-20 armor for free will be provided in the near future."
I have no clue where this is, if it's been implemented, or when it will be, but we will be able to freely upgrade past crafted armor to match the changes ArenaNet made to them.
