Can I move (a) record(s) from one base to a different base?

I setup one base a while back…and entered a few records in it, but didn’t keep using it.
Since then, I created a new base that now has over 1300 records in it.
Can I move the records from the original base into the new base? or somehow merge the bases together?

Export the table as a CSV, then import the records into the other base using the CSV Import app:
