I am trying to port a running cesm configuration (ver: 2.1.0) from one machine to another. I have copied over the folders in cesm.sandboxes/cesm2.1.0 from the source to the target machine. I have compiled and run the code successfully on the source machine and want to continue where I left off, but on the target machine. When I try to execute create_newcase on the target machine, I get an error message saying the "--run-unsupported" flag (which I require) is not a valid argument for create_newcase. Indeed, when I execute create_newcase -h, that flag does not show up as one of the arguments. But when I execute the same command on the source machine, the flag does show up as a valid option. Does someone know what might I be doing wrong? Should I try to pull the source code using git rather than copying them over across the two machines? I thought because those folders do not have any machine-compiled stuff, it should be okay to just copy them over. Any help is appreciated.
