Migration Server from Parallels Confixx to cPanel (Webhosting Software) - repost 2

Hello, i have a Server with Parallels Confixx (yes, the company from Plesk) Webhosting Panel, that is not more supported. They offer a migration tool from Confixx to Plesk, but i want migrate to cPanel. The Confixx Panel have no root-system like Plesk or cpanel(which controls all system), the services are standalone, My system is: Debian 6, Apache2, php 5.3, mySQL 5.1, postfix, dovecot as POP3/IMAP and proftp Username praefix are: web123,web124,.... the clients directory structure are: like /var/www/web123/html/ Database username are: web123 Database name are: usr_web123_1 , usr_web123_2 (1,2 stands for database1, database 2, a user have only one mysql-pass for all database) email username: web123p1, web123p2 (username for mailboxes) - FTP logins are same with login to control panel. what must be migrated: There are about 1000 users, with small pages html or cms like joomla/wordpress with their - FTP Files (by sync must be no problem) - Email-Adresses, Mailboxes (Dovecot-IMAP/POP3), E-mail redirects, auto responder - MySQL Databases (ver. 5.1) - php configurations: safe_mod, mod_rewrite, allow_url_fopen, allow_url_include - Subdomains (in cpanel they are named : parked domains), subdomains with redirect to another URL - statistics (awstats) the userdetails are only: Name of Customer, mail-adress and password. so its not a manually migration(by hand). because the current webserver(apache2),mailserver(dovecot),ftpserver(proftpd) and others is the same system with cpanel, should be not complicated. if the usernames for mysql-databases cannot implement in cPanel, then must be written a script, that replaces the login datas in php-scripts etc. but without touching the mail passwords. i provide a performance KVM VPS with cPanel installed, where you can use it to test the migrate.(with possibility to reinstall system) the finally migration will be in a new dedicated server. i uploaded here the database structure of Parallels confixx, so you can look at this.
