How can I move my backup files from old TIme Capsule to new Time Capsule?

SInce five years I use a TC 2TB. It is also the main cabled router in my Lan.

Have the new TC same router feautures?

If I buy the new TC I would like to transfer the backup files stored in the current TC. Is it possible? How?

Thank you so much for your support.
