officially this is done via do-release-upgrade.
which iterates through the list of available systems and updates the repository pointers to the new version.
then it independently launches apt to update the system, etc. etc.
but some jamb was found that kills the boot of ubuntu on some kind of macbook because of some troubles with UEFI, so 21.04 has not yet been included in the list of available systems.
and do-release-upgrade won't update anything for you.
at the moment it is possible only with handles in /etc/apt/sources.list and others like them to change groovy to hirsute and only then update the system via apt.
ps: I advise you to use aptitude to clean the system from obsolete and unnecessary later.

Not the best option.
Better clean ...
