OS Migration from Windows 2003 cluster to Windows 2008 R2 MSCS

[former_member319296]

We want to go for windows 2008 R2 server ( 64-Bit) MSCS by migrating from windows 2003 Cluster ( 32- Bit) . We are running on ECC 6.0 and oracle 10.2.0.2 DB.

Is it possible ?

Is it traditional System copy if so how to migrate the cluster ?

Sure its possible. You can do a simple homogeneous system copy to migrate to the new box.

Always check PAM regarding the target software

Hi Juan ,

I am just not sure about the Cluster migration.

1. As the target OS is windows 2008 R2 and as per note 1476928 it does not support < ECC SR3 . If the source SAP is running on ECC SR2 then does we need to upgrade it first to SR3 or we can directly migrate to the windows 2008 OS.

2. If the oracle version is 10.2.0.2 then does it will support Windows 2008 R2.

I think you are pointing to the wrong note,

Check Note 1476239 - SAP system migration to Windows 2008/2008 R2

You need at least 10.2.0.4 (you need to install that version with a separate DVD, you can't install with the normal Oracle DVD (10.2.0.1). See

Note 1303262 - Oracle on Windows Server 2008

Be aware of the fact that the normal standard support for 10.2.x is ending at end of july (you'll have to pay an extra maintenance fee if you continue to run that version) - see

Note 1110995 - Extended maintenance for Oracle Version 10.2

So if you now do a system copy to new hardware with a new os anyway, I would upgrade to 11.2.
