I eventually took the plunge and updated. (I had to wait for a long weekend) when there was little risk of user interruption). The upgrade was remote via SSH.
First tip:
Keep a journal, or open a text editor where you can write things down - passwords, pathnames etc. Copy and paste any messages you feel are important.
The install to ubuntu from 8.04 to 10.4 went ok. I followed the instructions here:
https://help.ubuntu.com/community/LucidUpgrades
NOTE: I was tense about the warning about the /boot/grub/menu.lst but this went without problem. You may just need to recheck if you are unsure.
I decided to upgrade to ispcp-omega-1.0.6.tar.gz, according to the instructions here:
http://isp-control.net/documentation/sta...ion:ubuntu
However, I found the document doc/Ubuntu/INSTALL to be a far greater source of information and recommend this.
I downloaded the ubuntu-packages-lucid.txt file attached here:
http://isp-control.net/forum/thread-1074...l#pid81799
and copied it to
docs/Ubuntu/ubuntu-packages-lucid
so that step 3 on the WIKI page could continue.
In step 8, I ran
perl ispcp-update
instead of
perl ispcp-setup
