Hi,
I do not see how to import the list in csv format created with the easy profile export?
You can find import tool at Components->Easy Profile->Import Users (see screenshot)
Just to be sure: with "all the fields of Joomla" you mean core Joomla fields or Joomla core fields + Joomla native custom fields?
If you need to import only Joomla core fields then you can simply use Easy Profile export/import features (of course export with EP is possible if your old site run Joomla 3.x). Instead if you need to import also Joomla native custom fields then I recommend you to copy DB table contents from old site
