lsload and lsdump

unknown

I need to move some security classes to production from out test environment. But I need to overlay some that is already in production. Can you tell me what parameter I need to do this? Is it the -o on the lsload?

You are correct.
The system will then initialize the Security Class in PROD first, and then create a new version of the Security Class.
Ensure that the new version of the Security Class is assigned to the corresponding Role(s).
