OS migration from 32 bit to 64 bit
I need to do OS migration on our ECC5 server installed on Windows 2003 server with oracle 9i database.
I have gone through several sap notes and have some doubts:
1-OS migration from 32 bit to 64 bit is a homogeneous or hetrogeneous system copy.
2-If it is homogeneous copy then I have performed that activity but that i did it for copy from PRD to DEV and bit version was same so would this 32 bit to 64 bit copy be same of that or i have to do some additional steps.
3-I also read that Oracle 10.2 is only installed on 64 bit,please confirm if it is right then i think i have to do first database upgrade on 32 bit system from 9i to 10.2.
