Antwort auf: Wechsel von Ledger zu Trezor

> 1. Can i just buy a Trezor on and ‘recover’ it with my existing ‘Ledger’ phrase?

Yes, be aware however, that very early firmware versions used non standard derivation path for Ethereum addresses. In that case you’ll have to move funds to trezor address

> 2. after that, what will happen with the ledger? can i have two wallets with same phrase

Yes you can have two wallets with the same phrase. Both can send transactions, and will see all incoming ones as well
