Hi guys!! I have an eth software wallet (myetherwallet) and I want to buy a trezor one but I would like to keep using my current address. I know that my wallet is safe because I have always use it offline and in a linux system without desktop. Is this possible?? Thanks in advance
(un)fortunately that is not possible since those addresses (Trezor and MEW one) are derived from different private keys (recovery seed).
So in order to use Trezor derived addresses you have to transfer your funds on such addresses doing regular transaction (covering the fees).
