Look at the docs on OTN
The 32 bit files are fine.
You just need to recreate the control files and recompile all stored code.
Sorry forgot to mention that we are in 10g release 1....
Now I have a brand new box with 64 bit oracle installed. Not upgrading, it is a new install. I am just trying to find out the easiest and fastest way to do the data movement. Trying to avoid exp from 32 bit and imp into 64 bit. So thought about bring the hard drive containg data from 32 bit machine to the 64 machine. If I create the tablespaces on 64 bit and point the datafiles to the disks that I brought over will that work?
