I recently installed High Sierra (10.13.4) over Sierra (10.12.6). Everything went fine and I am having no problems.

I did notice there was a Previous System Folder (2.2 Gb) after the installation.
Is it okay to delete that folder or should I leave it?

I don't see any problems by deleting it.

If you want to "take the careful route", do a full cloned backup of your boot drive as it is now (before deleting), and THEN delete it.

That way, if the results don't pan out as expected, it will be easy to "get back".

But again, the old System files are put into the "previous system" folder for a reason -- to make them easy to get rid of...
