The 2950's are a bit dated, so unless you have in excess of 4GB RAM, you 
don't need to move to 64-bit.  If you do choose to go 64-bit, I agree with 
the other posts, simply do a fresh install.  In doing a fresh install, save 
off the package list you have on the i386 build and reinstall those 
packages on the new 64-bit system.

Doing a fresh install will also save you time, since you can go right to 9, 
rather than doing two upgrades.
