my mtx armour set doesn't port from POE 1 to POE 2

Hi , i have a question about the recent rot shaman set from POE 1 , it seems the armour set doesn't port to POE 2. does this means my rot shaman set is hyper specific content item? or maybe in the next patch it will eventually get ported to poe 2.

side note : both of my poe 1 and poe 2 are connected through steam
