Good question. [Alby Hub provide only a migration procedure here](https://guides.getalby.com/user-guide/v/alby-account-and-browser-extension/alby-hub/faq-alby-hub/how-can-i-migrate-alby-hub-to-a-different-machine)

I would suggest to do a SCB backup separately if you use LND.
For the LDK, follow these instructions:
