Migrate a Conda Environment

Do the following steps to export a Conda environment.

  1. Open Anaconda Prompt and activate the environment you want to migrate. 
    conda activate <name_of_environment>
  2. Export the active environment. 
    conda env export > environment.yml

Import this environment file into a new machine.

  1. Open up Anaconda Prompt and go to that directory which has environment.yml.
  2. Create the environment by running: 
    conda env create -f environment.yml

To update an existing environment name with a new file:

conda env update --name myenv --file new_environment.yml --prune
