- For major updates, utilize our clone feature. This involves cloning the application stack and data from your current instance on an end-of-life OS (e.g., Ubuntu 20.04) and deploying it to a new instance with the latest OS version (e.g., Ubuntu 22.04).
- This cloning feature is accessible to all our customers.
- After cloning, review and ensure everything is functioning properly before redirecting your DNS from the old instance to the new one.
