I believe you can do this using RMAN.... Off the top of my head:

1. Upgrade to 10.2.0.4 in place on the 32 bit box. Upgrade the EE at the same time.
2. Use the transportable tablespace features of Oracle to move the datafiles. I think (though I've never done it) that you can move the datafiles from 32-bit to 64-bit without converting them. Looking at some Doc this appears to be the case, but I'd do a small test first to be sure. If you have to convert you can use RMAN and cross-platform transportable tablespaces, move from the 32 bit box to the 64 bit box.
3. Fire it up.

Bada boom, you are done.

Greetings,

One of my databases is Oracle 10.2.0.3.0 SE running on 32-bit RHEL4. I am building a new server running 64-bit RHEL4 and I will install Oracle 10.2.0.4.0 EE on this server. My goal is to move the existing database to the new server. I am hoping to do this using the cloning feature of the OEM provisioning pack and wondering if this will work smoothly. The concerns I have are

1. going from 32-bit to 64-bit
2. going from 10.2.0.3 to 10.2.0.4
3. going from SE to EE

I am pretty certain this isn't going to work, I don't believe OEM and RMAN have the intelligence built in to make the changes and I suspect I will have to use expdp/impdp but am just wondering if anyone has any further thoughts. Unfortunately I don't have an environment in which to test this.

Thanks.
