With most wallets you do not need to do any steps, just use your ecash. Receiving new ecash automatically uses new keyset. As you send your existing balance and receive or topup, ecash rotates over time.

Oooh! I receive an error:
Error receiving tokens: Error: Could not get fee. No keyset found for keyset id: 001079....65
Oooh! and when sending sats I get "keyset id inactive."
Which wallet?
@calle is the dev, best would be to get his advice.
Ooooh! I used the restore wallet option and now it works
