Your python script is looking for the clean.ucs file on the f5’s Linux directory. Does that file exist? If not, that explains the errror. It might also fail to read the file if the credentials are wrong, so confirm that the python script creds can log into that f5.

Thanks, There is There is "f5-[indtance ID]-clean.ucs", but not "clean.ucs". Is the file created by script? I originally stored only f5-aws-migrate.py, restore-clean-ucs, and save-clean-ucs. I think password and creds are correct because I succeeded in logging in the new instance.
