I am doing SCM 7.0 EHP3 upgrade from SCM 7.0. During execution phase the below error occured.
Severe error(s) occurred in phase MAIN_SWITCH/STOPSAP_XCNV!
Last error code set: Process /usr/sap/SID/DVEBMGS56/exe/sapcontrol exited with 1, see '/usr/sap/SID/SUM/abap/log/SAPup.ECO' for details
I can see the " FAIL: NIECONN_REFUSED (Connection refused), NiRawConnect failed in plugin_fopen ()" in SAPup.ECO file.
I could able to do "stopsap" manuall in main instance and it was successful. I have stopped all the running processess except the SUM tool.. still no luck.
I will appreciate all your help and guidance to resolve this issue.
Thanks a ton
