SAP Homogenous Migration
We have SAP CRM 2007 and BW on NW 7.0, running on windows 2003 x64 and Oracle is the DB and we wanted to upgrade our SAP Version from NW 7.0 to NW 7.4 with latest SP and CRM 2007 to SAP CRM 7.03 latest SP.
Our Oracle version is Oracle 188.8.131.52..
Our New landscape will be on Windows 2012 x64.
But as per PAM we cannot migrate our existing system to Windows 2012 by DB restore as PAM Doesnt support SAP NW 7.0 on Windows 2012 x64 also CRM 2007 is also not supported on Windows 2012 x64.
Also, if we want to upgrade SAP first to the latest on the Windows 2003 x64 i.e NW 7.0 to NW 7.4 and CRM to CRM 7.03 and then migrate to New OS i.e windows 2012 is also ruled because NW 7.4 and CRM 7.03 is not supported on Windows 2003 x64.
Need your advice on moving our existing servers to the new landscape.

SAP NW 7.0 is supported on Windows 2012 Server with Oracle 11. Please check PAM link below
So for this you can directly migrated and then upgrade to NW 7.4
CRM 2007 is supported on Windows 2008 R2 with Oracle 11 but not supported on Windows 2012.
So for CRM approach should be
1) Migrate CRM 2007 to Windows 2008 R2
2) Upgrade CRM to CRM 7.03 on Windows 2008 R2
3) Upgrade OS to Windows 2012
Hope this helps.
