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