Armor , Weapons from 1.0, Unobtainable in ARR?

I'm looking at the ilevel 52 armor that used to drop from cutter's cry and aurum vale. They are in the eorzea database in arr, which means they are physically in the game. In 1.0 they were ilevel 45. How does this work? Did you get them in 1.0 as ilevel 45, then they were upgraded to ilevel 52 when you carried them over to arr?

The reason I'm asking is because I like the look of Thormoen's Subligar for my tank, but there seems to be no way for me to get it since I didnt get 1.0.

SE stated all weapons and armour in 1.0 were moved to ARR - that said, a lot of pieces had their stats changed. And some equipment indeed seems to be no longer attainable (like the Hermes Shoes for instance).

As ilevel, this is a new system for ARR and was not in 1.0 - from what I understand ilevel is a separate grading system of a piece of equipment's relative strength and usefulness - it may not necessarily correspond to the actual level of the item that you can equip it (for instance, an ilevel piece of 50 might be equippable at level 45, like AF). But someone else should be able to clarify this.
