If you want to change the name of a space in your Cloud Foundry organization, you can follow the steps below.
Please note: if you would like to change the name of a space you need to have the space manager role for that space.
Login to cloud.gov using Cloud Foundry CLI:
cf login -a api.cloud.gov --sso
Use the CLI to target the organization containing the space that you would like to rename:
cf target -o ORGNAME
Once you have targeted the correct organization, run the cf rename-space command to rename the space:
cf rename-space SPACE NEW_SPACE_NAME
