To redeploy an environment, you can either use the CLI or the console. Redeploy uses the existing code and it's like rebooting your server/laptop. There will be some downtime when you redeploy but it's fairly short.
Run the following command:
platform redeploy
From Console:
- Select the project with the given environment.
- From the Environment menu, select the environment.
- Click More.
- Click Redeploy.
