Registration should be done newly if you left the country and moved again, given that the apartment is the same and the old TM30 is on hand?

Yes you need to.

You need, if you want to interact with the state, such as obtaining rights, opening an account or something else. If not, then it is still necessary, but in fact not necessarily. I lived quietly for 45 days without registration and made another border.
