Need Help on peoplesoft adapter

Hello Experts!

I don’t have much experiece on Peoplesoft adapters and these days i m kinda messing my head with lot of problems there.

My problem is I have migrating peoplesoft adapter interfaces from webMethods 6.5 to webMethods 8.x now, source systems are not gonna to change, so i took the same Complied class files (API files) for all components interfaces (CI) from webMethods 65 systems. Although connection is working fine but i am able to access these CI’s hosted in peoplesoft server.
Do i need to again generate the API files and compile them before putting into wm8? theoritically copy from older systems should work but dont know why i am getting authorisation error…

Please share your ideas on this problem.
