The question I have for you Dave is why migrate at all?
Contrary to popular marketing many 64 bit instructions execute more slowly than 32 bit ones - especially in older processors such as the one in your K250. The speed benefits of 64 bits come in accessing more memory, supporting more users at once, being able to cache more data therefore reducing i/o. The technical documents on migration to 64 bits all tell you this, see:
http://docs.hp.com/en/5966-9887/ch01s02.htmlhttp://docs.hp.com/en/5966-9887/index.htmlAlthough those documents were about 11.00 not 11.11, a lot of it is still relevent.
The other thing that springs to mind on this is that the maintenance on your old K class must be so high now that it might be cheaper (over 3 years) to purchase a new rp34xx with a new much faster processor, more memory, faster disks and up-front maintenance. Then you would not have the problem of an in-place upgrade to worry about. You can test your apps on the new machine and cut-over the data when ready. I did this exercise on our K360 and will be saving a few thousand by 2008.
