OS Migration from AIX to Windows

[former_member227150]

Hi,

We are planning to migrate SAP R/3 Enterprise 4.7x110 from AIX 5.1 to Windows Server 2003.

The existing solution is on Cluster and we want the target system to be without cluster. So, is it possible to go with this scenario?

Is there any specific pre-requisites to be followed?

Can anyone share some guides / references for this ?

Thanks,

Gaurav

Hi Gaurav,

In addition to the excellent advice above, ensure you read the migration guides thoroughly first so that you get all the latest tools.  And practice, practice, practice this process to get it smooth. 

Of course, if you are going to do this for a production system, then you will require the assistance of a OS/DB migration certified person so that SAP will assist and sign off the migration.

In addition pay attention to endianess. Power is big endian, x86_64 is little endian.

Hi Gaurav,

There is no specific steps for migrating the system from cluster to non-cluster.    Please follow the below steps on your issue.

1.Take an export of your system using the SAP Virtual DB hostname. I mean using SAPINST_USE_HOSTNAME=<Virtual DB hostname>

2. Install DB in your windows server.

3.Import the data in your windows.. During installation, just select the normal method of system copy like WITHOUT High availablity installation..

I have attached the first sapinst screen for the options you need to choose. Here i have choosed Non-unicode as the system which I have migrated is a non-unicode.. Please select accordingly to your system

I believe the information helps.

Thanks and Regards,
