My tezos are currently baking through a delegated, KTZ account, created from a software-based TZ1 account (created with Galleon). I now have a hardware wallet (Ledger) and want to transfer the delegated account to my new TZ1 account, so as not to interrupt the baking process. Alternative, I would have to stop delegating, transfer the funds to the new hardware-based TZ1 account, create a new KTZ account, and redelegate again. This involve fees (creation of KTZ account) and losing baking time.
Is it possible to transfer the delegated account to a different TZ1 account? I get the impression it is not possible (e.g. see here and here).
