ISPC 2 to ISPC 3
Mainly ISPC 2 does not store Passwords however in broad strokes
1. Get the passwords from the shadow file (use pwunconv) the encrypted does actually work
2. Re-create all the users and I used the encrypted passwds in an MySQL tool such as phpmyadmin
Its tricky as hel but make sure to TEST first before accepting this advice.
OFC the /var/www works fine and old mail - well all mail is rather volatile and thus sometime not worth bothering to transfer however use fetchmail if you need to or the build-in fetch from ISPC3
