Hello

I would like upgrade SLES 11 for SAP SP3 to SLES 11 for SAP SP4 to get upgrade hana DB SPS9 to SPS 12.
I update SLES 11 SP3 to the last patches and then the tray "gnome-packagekit" displays a message that a distribution upgrade is available.
I am using the "guide" https://www.suse.com/es-es/support/kb/doc?id=7016711 the steps from this guide are valid to "SUSE Linux Enterprise Server 11 for SAP Applications".
But when I follow the steps it tells me that it remove the "SUSE_SLES_SAP-SP4-migration" package and I think that is wrong.
Or really, it is right and I have to follow these steps then I will have to add the package later and I will run the script that says in note https://www.suse.com/es-es/support/kb/doc?id=7016707 and then the system will reach to SLES 11 SP4 for SAP.
Or directly I have to run the script that says in note https://www.suse.com/es-es/support/kb/doc?id=7016707 and then the system will reach to SLES 11 SP4 for SAP from SLES 11 SP3 for SAP without any previous step.

Regards
