The NKT system introduces a host map feature for managing container migration. Users can initiate the process by selecting the migration button and dragging containers or entire stacks to a new host block. The system offers an immediate application switch to execute the transfer without additional prompts if no warnings are detected.
The migration process consists of four stages: packing, transferring data via a hub, unpacking on the new host, and the Traffic Fly phase. During Traffic Fly, the system waits 90 seconds for the new gateway to confirm the service is active before switching traffic. If an error occurs, the system automatically restarts the stack on the original host.
The platform supports rollback functionality, allowing users to revert to the old host by clicking on the grey tile. This action stops the new stack and restores the original configuration. Users can also perform a rollback without the new host if it becomes unresponsive. Once the migration is verified, the old stack can be removed from the system.
