I have a cold storage multisig created with Electrum.
When I initially set that up I unknowingly let the Electrum app connect to a number of public Electrum servers, losing privacy as it shared a lot of my unused receiving addresses (not sure how many).
Today Electrum is connected to my private Electrum server. I want to mix my UTXOs and send them to a new set of addresses without having to reset the BIP-39 mnemonic.
I tried changing the derivation path from: m/48'/0'/0'/2' (default) to m/48'/0'/1'/2' to create a new account in Sparrow (as multisig watch-only for now) but it keeps showing me the old addresses/UTXOs.
Do I need new Zpubs when changing the derivation path? If so, how to obtain them?
Should I use Electrum to create a brand new wallet/account and specify a different derivation path? Would m/48'/0'/1'/2' make sense or do I risk losing funds due to some future incompatibility?
