Hello Sel,
Before starting this migration, ensure you have the minimum SPS as per note 1651862:
Required minimum SAP Netweaver Support Package Stacks (SPSs) for SQL Server 2012 (SAP ABAP, SAP ABAP+JAVA stacks)
SAP NETWEAVER 7.0 - SPS 26 (SAP BASIS 26, SAP BW 28)
SAP EHP1 FOR SAP NETWEAVER 7.0 - SPS 11 (SAP BASIS 11, SAP BW 11)
SAP EHP2 FOR SAP NETWEAVER 7.0 - SPS 11 (SAP BASIS 11, SAP BW 11)
SAP EHP3 FOR SAP NETWEAVER 7.0 - SPS 03 (SAP BASIS 03, SAP BW 03)
SAP NETWEAVER 7.1 - SPS 14 (SAP BASIS SP14)
SAP EHP1 FOR SAP NETWEAVER 7.1 EhP1 - SPS 10(SAP BASIS SP10, SAP BW SP10)
SAP NetWeaver 7.2 - no restriction
SAP NETWEAVER 7.3 - SPS 07 (SAP BASIS 07, SAP BW 07)
SAP EHP1 FOR SAP NETWEAVER 7.3 - SPS 03 (SAP BASIS 03, SAP BW 03)
SAP NETWEAVER 7.4 and higher - no restriction
If your system is running on a SPS lower than the one required above, you have to apply the minimum required SPS before upgrading/migrating to SQL Server 2012.
If you install a NetWeaver product on SQL Server 2012, the required SPS for your product must be applied immediately after the installation - see SAP note 1676665, section I for more information.
