SAP Windows 64 bit Compatibility

Dear Friends,

1. Currently we have SAP ECC5-Oracle 9.0.2-Win 03 ( 32-bit)

2. We are moving to SAP ECC5-Oracle 10.2-WIn03 (64-bit)

3. We have 3 system LS ( DEV - QAS - PRD)

Our Plan : We want to move DEV first to 64bit and do testing for 1 week then move QAS 2nd week and later move PRD in 3rd week.

Q. Is it compatible to move DEV to 64bit and keep other systems on 32bit while testing is going on.

Are there any issues in maintaining 32 and 64 bit versions on same Land Scape.

(OR)

Do we need to move all three ( D, Q and P ) at one time to avoid any incosistency.

Thanks & Regards

Pradeep.G

    1.- Yes you can have one system in 64 bits and another in 32 bits with no problem (I have seem that in 3 different companies).

    Go on and keep with your plan that is the logical way to do it, you could test with DEV system and then the next weekend do QA and PRD at the same time because should not be any problem at all with this change but QA test is not a bat idea either.

    I don´t recall if you can upgrade from 9.2 to 10.2 and at the same time move to 64 bits (I think you can). The way I have done that is moving 10.2 from 32 bits to 64 bits using an homogeneous system copy but that was under Windows.

    No.

    I would keep the OS bitness the same across your landscape. There may be cases where you can´t e. g. run some big reports on 32bit systems due to its memory limitation so you won´t be able to test them. Technically it´s not necessary to move.

    Pradeep,

    We are considering going to 64 bits, the OS is Windows 2003 Server, two servers clustered with the potential of upgrading to Windows 2008 Server, two servers clustered. In your transition what issues did you encounter?
