Upgrade Script

[riser]

Hi Jerry,

I plan on testing this process sometime this month.  I was not looking forward to a full clean LL 2.2 install given all the customization I have make, but always wanted the increased speed and latest packages.

I took a look at the script and would like to suggest some code changes for easier maintenance and reduced overhead.  Feel free to ignore, and I must mention this code is not fully tested (I tested bits of changes to ensure the resulting commands are equivalent).
