Upgrading ECC 6.0 (SAP Kernel 7.20) from Oracle 10.2.0.5 to Oracle 12c
We have an installation SAP ECC 6.0 , SAP Kernel 7.20 on Solaris SPARC 10, and Oracle 10.2.0.5. Now we want to upgrade to Oracle 12c.
we have read a lot information and OSS notes and we have a pair of doubts not clarified:
1.- What is the final version of SAP Kernel recommended for SAP ECC 6.00 , Solaris 10, and Oracle 12c ?
As per note 2133079 - Oracle Database 12c: Integration in SAP environment is SAP KERNEL 7.21_EXT and above
As per service.sap.com/PAM SAP KERNEL is 721_EXT or 7.22_EXT
So, 7.22 (no EXT) is compatible is possible???
Is SAP Kernel 7.22 (or 7.22 EXT) stable? I have seen on sap service marketplace lastest SAPEXE and SAPEXEDB packages are not complete. SAPEXEDB are missing...
2.- During Oracle upgrading process... is necessary switch SAP kernel from 7.20 to a temporal sap kernel higher than 7.20 (but not the target kernel) in certain moment? or is possible perform all necessary tasks related to oracle upgrade without changing sap kernel, and then at moment final switch to sap kernel 7.22_EXT (i.e) ??
Thanks and regards
