Migrating from AIX to Windows

[Former Member]

Hi all,

We are considering in a SAP R/3 4.6c to ECC6 Upgrade, the option to migrate from AIX to Windows OS.

We heard that this option is not so usual.

- Could you tell us some feedback and recommendation about it?

- What kind of issues will we face?

Thanks for your help,

Chris

Be aware of the fact, that you need to have a migration consultant on-site, otherwise you will loose support for the target system:

Did you actually READ the guides on the page I pointed you to?

I repeat again: Migrations must be done by certified consultants.

Hi,

I will add an other check to Markus very good points :

If you have specific interface programs dealing with files, check that all accesses to the files is done through logical paths and logical files from transaction FILE.

If you have application servers (dialog instances) , you need to use shared directories with UNC syntax (something like
<P=SAPMSHOST>\dir\subdir\<FILENAME> )

Usual? What is "usual"?

This depends heavily (if not only) on your environment. Some thoughts:

- Windows is little endian whereas AIX is big endian; this may affect connected software (non-SAP software, filesystem transfers etc.)

- additional software plus licenses may become necessary (cluster, backup...)

- do you have enough knowledge about Windows (+ its internals) as you have on AIX? Windows is not "easier" by default just because you have a mouse to click... (even if everyone thinks it is). Windows administration is totally different to any *nix (you may need to change scripts, consider updating regularly, think about problems you didn't have before (Virus, Worms) etc.)

- Hardware for Windows is usually cheaper than Power based hardware for AIX

- Windows licenses (+ CALs) must be bought

Just as another thought: Did you consider running Linux instead? You will use the same (cheaper) hardware with a more common environment (if you come from AIX)?
