64-bit SSIS

Newbie question on SSIS and 64-bit....Looking for pointers ...Thx in advance...
Can we develop SSIS pkgs on 32-bit machines and deploy to 64-bit?
Any software needed on 64-bit machine , like .NET 2.0 64-bit, etc...?
Any knobs/switches to do during deployment, to ensure pkg runs on 64-bit...?
Any gotchas...things to be aware of...?

If accessing SAP, SQL, Oracle, do OLE DB .NET drivers need to be 64-bit as well, if PKG is running on 64-bit machine...?

if developing SSIS pkgs on a 64-bit machine, any issues to be aware of?

Thx again

Yes, in fact that is the way you're supposed to do it for Itanium servers since VS isn't supported on IA64.

No, 64-bit .NET 2.0 will be installed by your SQL 2005 setup process.

Not really. Script tasks have to have PreCompile=true to run on 64-bit. This is the default setting.

Maybe. In my experience the Excel OLE DB Provider doesn't work on X64 (haven't tried it on IA64). Also, debugging Control Flow script tasks doesn't work when PreCompile=true (which is req'd for 64-bit). You can't debug Data Flow script components on either platform.

I don't know for sure, but the Excel problem above is probably a decent indication. Might depend on the provider.

I've not had any platform-related problems developing packages on an X64 server. Again, Visual Studio isn't supported on IA64.

Jay|||The absence of the Jet OLE DB Provider (which means Excel too) and the requirement of precompiled scripts seem to be the 2 most obvious limitations that you're going to run into on 64-bit.

Please see the BOL topic, "Integration Services Considerations on 64-bit Computers," for a summary of other considerations, most of which were touched on above.
