Nostalrius Begins - Quality wow vanilla realm (1.12)

Hi, i have bought pvp chest couple of months ago. Since then they updated it to the newest patch. But my chest stayed outdated, today i bought boots and it didnt match with the chest for set bonus. I have both items at 1/6 set.

Would it be possible to get my chest updated?

Sincerely, RandomJoe

You have to purchase the new items at the vendor. They didnt update the gear, they replaced it with new.
