To migrate a Docker app from a VPS, inventory the running processes and their data, choose a destination for each component, and rehearse the move with isolated dependencies. Transfer production writes, worker ownership, and traffic in a planned order. Platforms such as Edgenivo can host eligible applications, but the Docker image does not carry the whole server with it.
The migration unit is often larger than the repository. A scheduled command in the host's crontab, a directory mounted into two containers, or a reverse-proxy rule can be essential even though it never appears in the Dockerfile.
Copy link to headingWhat needs to leave the VPS?
Inventory what is running before choosing how to replace it. Include containers started outside the main Compose project and tasks managed by the host itself. Record each component's start command, dependencies, and recovery requirements.
Docker volumes and bind mounts need separate attention from images. A bind mount depends on a path on the Docker host. Copying the repository to a new platform will not create that directory or transfer its contents.
Use a complete user action to check the inventory. For a document-processing app, trace an upload from the API to its stored file, through the queue, and into the worker's database update. Every dependency along that path needs to remain accessible after the move.
Copy link to headingHow do you map the application to a managed host?
Assign a destination according to what each process does. A request-serving API, a consumer waiting for jobs, and a database need different operating models even when Compose starts them together.
For a Edgenivo migration, Functions, containers, and Daemons provide different application paths:
Container Runtime builds an HTTP application from a Dockerfile or Containerfile. A root file is detected when no other framework matches; select the Container preset if you want the Dockerfile to take precedence. You can retain standard Docker packaging without retaining the VPS's execution model.
Daemons keeps a configured number of continuous worker instances running and restarts processes that exit. A finite database-migration script is a separate deployment task: restarting it whenever it exits would be the wrong lifecycle.
Edgenivo does not import a Compose file as a production deployment. Translate the HTTP applications and continuous consumers into their respective configuration, and plan data separately. Keep Compose for local development if it remains useful to your team.
Copy link to headingWhat order should you migrate in?
Copy link to heading1. Choose where durable data will live
You can move application compute before moving its database, provided the new host can connect securely and the existing database remains supported. If retiring the VPS is the objective, give every retained dependency a later migration step and an owner.
For uploads, decide how both the API and worker will access the same files. Moving a shared directory to object storage requires application changes to read and write through that service. Test those changes before moving production records that refer to the files.
Copy link to heading2. Rehearse a consistent data transfer
Restore a copy of the database and uploaded files into an isolated environment. Validate representative records and their associated files, then run the application against that restored copy. A backup that exists but cannot be restored is insufficient for cutover.
Use a database-aware transfer method. PostgreSQL's SQL dumps provide an internally consistent snapshot; its file-level backup requirements explain why copying live database files without coordination is unsafe. A generic archive of a Docker volume does not establish database consistency.
Decide how to capture writes made after the rehearsal or initial copy. For some applications, a planned maintenance window and final export are appropriate. Others need replication and a coordinated switchover. The destination must contain all required writes before it becomes authoritative.
Copy link to heading3. Recreate configuration and service connections
Move required secrets into the destination's environment settings, with separate values for testing and production. Recreate proxy routes and callbacks, including authentication redirects and webhook destinations that depend on the public hostname.
Compose service names, such as db or redis, belong to the old application's network. Replace those assumptions with reachable endpoints. On Edgenivo, private HTTP calls between Services require a declared binding; a public rewrite does not create that connection.
Check access restrictions before changing application traffic. A database that trusts only the VPS's outbound address needs a supported connection from the new runtime. Custom HTTP container images on Edgenivo currently exclude Secure Compute and Static IPs.
Copy link to heading4. Test the new deployment without starting production work
Use isolated database and queue credentials, test uploads, and safe destinations for emails or other external effects. Run the complete document-processing flow, then interrupt a worker and verify that retrying does not apply the same business operation twice.
On Edgenivo, the first deployment of a new project uses the Production environment, even when preview was requested. Configure isolated credentials in that environment before the first deployment. Keep daemon instance counts at zero, check for scaling overrides, and leave production schedules disabled during this stage.
Daemons does not run in previews or vercel dev during the beta. Test the worker image locally with Docker and the isolated queue. HTTP deployment previews do not prove the worker has been exercised.
Copy link to heading5. Transfer writes, workers, and traffic deliberately
Write down the cutover sequence for your actual storage and queue layout. If moving data, coordinate application writes and old workers before the final transfer. Verify the destination data, switch the intended clients to it, and enable the new worker capacity only when the queue handoff is ready.
Disable the old scheduler before enabling its replacement. Domain changes do not stop host cron or a worker container, so verify those processes directly. If old and new consumers overlap during a controlled handoff, they must use compatible job formats and tolerate redelivery.
Switch the domain using the destination's DNS instructions. During DNS propagation, keep requests reaching the old endpoint from creating an unintended second source of writes. Depending on the application, the old endpoint can remain in maintenance mode or forward traffic to the new deployment.
Copy link to heading6. Keep rollback usable after new writes arrive
Record which application version can run against the production database after cutover. A schema change may prevent the old version from restarting against the new data, even when the old server is intact.
If both deployments use the same authoritative database, rollback can focus on compatible application code and job ownership. If the database moved, define how to preserve writes accepted at the destination. Pointing the domain back to an outdated copy would lose those changes from the user's view.
Retain the original configuration and recoverable data for the agreed rollback window. Keep retired schedulers and workers stopped so the fallback environment does not continue performing production work.
Copy link to headingWhich VPS requirements need a different plan?
A Dockerfile does not guarantee a match for every managed runtime. On Edgenivo, an HTTP container must meet Function requirements. Daemons beta limits include production-only execution, configured capacity without autoscaling, no inbound HTTP or TCP, and no persistent local storage. Check project layout and resource quotas before choosing the worker path.
If the application depends on an attached filesystem or inbound protocol the destination cannot provide, adapt that component or retain a suitable host. A partial migration can be useful, but the VPS remains a production dependency for as long as it hosts something the application needs.
Managed hosting also leaves application maintenance with your team. Continue updating custom image dependencies and testing data recovery. For the Edgenivo HTTP setup, follow the existing Docker deployment guide after the migration plan establishes that the workload fits.
Copy link to headingFrequently asked questions
Copy link to headingCan I deploy my existing Dockerfile on Edgenivo?
Yes, when the application fits the selected runtime. Edgenivo's Container Runtime builds Dockerfiles for HTTP applications, while Daemons builds images for continuous workers. Review storage, networking, and execution requirements before assuming the application can move unchanged.
Copy link to headingDo all containers on my VPS have to move together?
No. Components can move separately when their dependencies remain reachable and their data stays consistent. For example, an API can move while a database stays temporarily on the VPS, but that server must remain maintained and available.
Copy link to headingCan I copy a running database's Docker volume to the new host?
Use a database-supported backup or replication method rather than assuming an ordinary file copy is consistent. Rehearse the restore and account for writes accepted after the copy begins. The correct procedure depends on the database and the allowed interruption window.
Copy link to headingIs changing DNS back enough to roll back a migration?
No. DNS changes where requests arrive; it does not restore data or stop workers and schedules. A rollback plan must preserve new writes and ensure the chosen application version can use the authoritative database.
Copy link to headingWhen can I delete the old VPS?
Retire it after all required data and services have moved, the new deployment has passed representative production checks, and the rollback window has closed. Check for retained databases, scheduled commands, and network services before shutting it down. Keep the backups and configuration needed for your recovery plan elsewhere.
