First time poster here.
I was trying to upgrade our Netweaver server from 7.1CE to 7.5 Java only. It was listed in one of the Notes to upgrade Kernel to 7.45.
In doing so I downloaded SAPEXEDB_100-80000795.SAR and SAPEXE_100-80000796.SAR, unpacked and put them in "<Drive>:\usr\sap\<SID>\SYS\exe\uc\NTAMD64". After doing this the SAP management console was in Yellow State and Further reading mentioned the Kernel Level and disp+work should be of same patch.
I followed by downloading dw_114-80000796.sar and putting all the contents again <Drive>:\usr\sap\<SID>\SYS\exe\uc\NTAMD64. This completely back fired with SAPSID_00 services not coming up and also manament console not showing any SAP services.
I restored the NTAMD64 folder with older contents still of no help.
Any help appreciated.
