endpointID when converting to new IBM I OS

Hi

When we migrate the “IBM I” LPAR’s to new hardware, is it then correct that we ned to change the endpointID in the computer.yml file, so it include the new HWserial number.

If the HW serial number changes then it should be updated in the computer.yml file. See the following link for computer.yml file details.
