32-64 bit migration, unicode conversion

[Former Member]

Hi,

I need to convert SAP ECC5.0 system running on windows 2003 from 32 Bit to 64Bit, nonunicode to unicode and need to upgrade oracle 9i to 10g. Can i do the three at a single go with export and import process. please suggest.

Thanks/gopal

Yes.

You can

- prepare the UC-conversion on 32bit (on 9i)

- on your new machine install Windows x86_64 + Oracle 10.2.0.4

- export the old system

- import to the new system

The last two steps can be done in parallel.

However, not that conversion is done during export, it may not be as fast as if you would do that on the 64bit platform (memory for database cache limited due to 32bit).

Another approach would be to install the 64bit system, do a system copy from 9i to 10g, which is possible in one step (Note 932722 - Upgrade to Oracle 10.2 during a database copy) and then do the UC conversion on the 64bit platform.
