Double upgrade - Ubuntu 8.04 to 10.04 and ispCP 2.03 to 2.05

[crafter]

Hi

My live server requires two upgrades:-

• Ubuntu 8.04 need to upgrade to 10.04
• ispCP 2.03 must upgrade to 2.05
  

I'm not sure which I should upgrade first.

An alternative is to upgrade the operating system, then do a fresh install of ispCP 2.05. The biggest issue is to retain the email user accounts and passwords. However, I'm not too sure of all the steps I need to take to save the accounts from 2.03 and load them into 2.05.

Can anyone provide some pointers to do this, or point out things that I should be aware of before embarking on this exercise.

Regards
