kernel upgrade

I am running crm 2007 (support pack stack 4). Below are the details of the differnt components.

software component release level highest support pack

SAP_ABA 700 16 SAPKA70016

SAP_BASIS 700 16 SAPKB70016

PI_BASIS 2006_1_700 6 SAPKIPYM06

ST-PI 2008_1_700 0 -


SAP_BW 700 18 SAPKW70018

SAP_AP 700 13 SAPKNA7013

BBPCRM 600 4 SAPKU60004

Kernel: 159.

When we applied support pack stack 4 this was the level to which all the components were brought to.

My questions:

1) Can I upgrade the kenel to the latest available (kernel 221) ? Is there any limitation as to what kernel level you can go to for a aupport pack stack ? Or can we go the latest and greatest ?

2) Similarly for the various softwarecomponents. Can I upgrade the differnet software components (sap_aba, sap_basis) etc to the latest available (release 20 coming in oct) ?

thank you


yes there is no upper bound, you can and you should keep the kernel the latest available
