if you install exactly the same OS then this may work:
copy: /etc/ispcp, /var/www, /var/mail, /var/lib/mysql (or dump the DB and insert the dump manually), then some other files in /etc:
init.d/ispcp*, postfix/*, poroftpd/*, apache2/*, cron.d/*, crontab.d/*, passwd, group, shadow, gshadow - maybe more???
then:
/usr/sbin/maillogconvert.pl, /var/log/somefiles if you want... - but create the folders!

if you use another hostname not that you need to make the changes...

But maybe it's better to install the newest OS release, install the newest ispcp and then try to import the data (db ispcp, set status of the fields to "toadd") - and later move the data (webs, mails, DBs) and check if the uids are the same!
