upgrade form .86 w/RC2

[londonhogfan]

I need to upgrade one of my sites to 1.1.2 and tp.97.1...  Can someone tell me I am doing it right before I go any further

Uninstall .97 (can I delete)
Upgrade to 1.1.2 SMF

install IchBins file stickied here for tp with 1.1.2 ( is this the entire version of TP or just a patch to the regular .97?)

done.  Sounds almost too easy.

Thanks, Jacob
