Unfortunately, even if you remember your legacy accounts's info, you ain't going to get your items back.
I tried login to several legacy accounts that haven't be logged after Aug 2017(where reloaded took place) The result showed all the legacy items will be deleted for no reason.
Who knows, maybe those accounts ain't useful to the game anymore, it's true, if memories were lost they are lost, how could you experience them again like you experienced them before
The only way that you could save your legacy items was logged on at least once after reloaded update, maybe before 2019-20 something
