OS/DB Upgrade to 64Bits what happens to Other 32bits on the transportdomain

Hi All,

I have an upgrade project ECC 5.0

Current state

Windows 32 O/S, ECC 5 32bits,Oracle 9.2 32bits .

Future State

Windows 64 O/S, ECC5 64bits, Oracle 9.2 64bits


My proposed plan

a. Offline backup the source system database

b. Use ORABRCOPY tool to generate the necessary oracle parameters

c. Install Windows 64bits

+d. Perform the SAP installation/Homogeneous copy.........


My Concern.

1) This system is part of the System Landscape i.e Dev,QAS and Prod; and we plan to do the upgrade in phases. What happens to the transport Domain. Is it possible to Transport from

ECC-Dev (64bits) to ECC-QAS(32bit) - ECC-PRD(32bits)

2) This system is also connected to an external 32bits 6.20 ITS. Will the connection still work i.e 64bits SAP ECC to 32bits External ITS based system.

Thanks for your help.
