The application AWStats is already installed at the server level in cPanel. If you have a lot of log data that you need to include with your move to cPanel, then you will want to migrate the data files for AWStats and copy them over to your cPanel account.
AWStats data is stored in /var/lib/awstats as .txt files. You need all of these files copied over to your cPanel account. The new folder will be /home/cpaneluser/tmp/awstats
