Airflow: Is there a way to copy variables from one Composer version to another Composer version using Cloud Shell?

Question

I am working on a migration task, which involves copying variables from one Cloud Composer version to another Cloud Composer version using Cloud Shell.

Though, is it possible to accomplish such a task in Cloud Shell?

I have read the Airflow and Composer documentation; though, I cannot seem to find a working command that will allow me to copy variables from one Composer version to another.

There isn't a single Airflow CLI command to "move" Variables from one Airflow environment to another; however, you can export Variables from source environment to a file and then import from the same file to the target environment.

Something like this:

Export from source environment

gcloud composer environments run SOURCE_ENVIRONMENT_NAME \
    --location SOURCE_LOCATION \
    variables export \
    my_file.json

Import to target environment

gcloud composer environments run TARGET_ENVIRONMENT_NAME \
    --location TARGET_LOCATION \
    variables import \
    my_file.json
