Plesk Migration MSSQL MylittleAdmin

hi, i want to move 2-3 websites of my client, he is using plesk + MSSql with MylittleAdmin, Now he wants to move on cpanel hosting. Can you guide me how to do that? i know the manual way of phpmyadmin taking export/import system and file manager for public_html directory. but in MylittleAdmin MSSql i don't know how to migrate.. i have moved his file manager files, struck in SQL. NO Plesk Server's root access he has.he is just a user of plesk hosting. for Cpanel, yes i have root access. Thanks
