Hi,

I am trying to upgrade Siebel 24.9 to Siebel 25.9 in vanilla environment. However, I am not able login to SMC and whenever I try to login, it gives me
"The user ID or password that you entered is incorrect."

The log file "siebelapplicationcontainer_siebel_home_c_siebel_xxx_external-stderr.2025-09-22.log"
in Siebel applicationcontainer_external shows the following.

Exception in thread "Thread-1" java.lang.NoClassDefFoundError: com/siebel/opcgw/cloudgateway/CGConfig
