[clue] 32 bit app, 64 bit OS

[David L. Willson]

Libraries are going to bite you.

This is what I would do:

Virtualize the whole box, and run it as a guest on the new hardware. You'll still get 85-90% of the performance you would have gotten with a full 64-bit stack.

Then, if you want that last 10-15%, migrate your data to 64-bit applications on the host machine, one at a time.

Enterprise's virtualization features are pretty sweet.

This is a good time for a r3VOLution.
