PaaS migration and cloud exit for production applications
WZ-IT moves applications from Vercel, Railway, Render, Fly.io, Heroku, Netlify and other platforms to Coolify, Docker, Kubernetes or another suitable target architecture. German, European and customer-owned infrastructure are possible operating locations.
Companies worldwide trust WZ-IT
Retain deployment convenience while replacing platform dependencies deliberately
The target setup should continue to support Git, automated builds and separate environments. That requires mapping every platform capability to a sustainable target architecture instead of moving only the application and domain.
Complete inventory
Code, framework, build, functions, environment variables, databases, storage, jobs, domains and external services are captured.
Suitable target platform
Coolify, Docker, managed infrastructure or another target architecture is selected around the application and operating needs.
Planned cutover
Test deployment, data transfer, functional validation, DNS switch and rollback checkpoint are defined before production moves.
Technical guides for Vercel, Heroku, Netlify, Railway, Render, Fly.io, target platforms and cutover.
Replace Vercel, Railway, Render, Fly.io, Heroku and Netlify with control
The technical path differs by source. WZ-IT maps the platform capabilities in use individually instead of promising a blanket one-to-one move.
Vercel to Coolify or controllable infrastructure
Port Next.js or other web applications with builds, functions, images, caches, cron, domains, and preview and production configuration.
Railway to own infrastructure
Move services, variables, databases, volumes, build and start commands to Docker, Coolify or a managed target environment.
Render to Coolify or Docker
Move web services, workers, cron jobs, persistent disks, databases and Blueprint configuration into reproducible target operations.
Fly.io to own infrastructure
Remap machines, images, secrets, volumes, networking and region logic, and connected databases for the target architecture.
Heroku to Coolify or container operations
Move Procfile, dynos, buildpacks, config vars, add-ons, workers, scheduler and Heroku Postgres to suitable runtime and data services.
Netlify to Coolify or static hosting
Export, replace or reconnect builds, deploy previews, functions, forms, redirects, headers and environment variables according to actual use.
Data, storage and background processes
Migrate databases, uploads, object storage, queues, workers and scheduled jobs separately and validate them against the application.
CI/CD, staging and production
Rebuild Git integration, builds, health checks, deployments, separated variables and optional preview or staging environments.
Domains and external integrations
Prepare DNS, TLS, redirects, webhooks, OAuth callbacks, email and third-party APIs for the new endpoint.
Monitoring and operations handover
Define logs, availability, resources, backups, updates and ownership for operations after cutover.
Effort factors
The specific scope depends on how deeply platform capabilities are used
- Serverless or edge functions that need adapting to a different runtime
- Large or write-intensive databases with a short permitted outage
- Persistent volumes, object storage and platform data without a direct export path
- Several applications, regions, domains or interdependent services
- Application defects, missing tests or architecture changes required before migration
- High availability, extensive preview environments or special compliance requirements
Inventory the source, reproduce the target, rehearse the move and cut over with control
The current platform remains in production until the application, data paths and acceptance criteria have been validated on the target environment.
- 01
Capture the source
Document repository, services, variables, data, domains, integrations and the current deployment process.
- 02
Prepare the target
Provide infrastructure, runtime, build, data services, network, backups and monitoring.
- 03
Rehearse the migration
Transfer application and data in a test run, validate user paths and resolve deviations.
- 04
Cut over and hand off
Move final data, switch the domain, complete acceptance and document the operating handover.
Starting price
PaaS and cloud-exit migration from €1,990 excl. VAT
€1,990 excluding VAT is the starting price for a clearly bounded migration project. A binding proposal is prepared only after assessing the source, target, platform capabilities, data and cutover requirements.
Individually scoped PaaS migration
from €1,990
excl. VAT, one-time
For moving a clearly bounded application or platform path to a prepared target environment in a controlled process.
Factors that determine price
- Number and coupling of applications and services
- Serverless, edge, cache and platform capabilities in use
- Database, storage and transfer volume
- Required code and architecture changes
- Staging, preview, availability and cutover requirements
- Required operations after migration
The starting price does not define a blanket service package. Before commissioning, you receive a documented scope, the planned target environment and a concrete project price.
When a PaaS or cloud exit is appropriate
- An application needs to move from Vercel, Railway, Render, Fly.io, Heroku or Netlify to controllable infrastructure
- Coolify or Docker should replace the current Git-based deployment process
- Hosting cost, data location or platform dependency needs reassessment
- Staging and production should be operated separately and traceably
- WZ-IT or a co-managed model with the development team should operate the application after migration
What we need for the initial assessment
- Current platform and desired target
- Repository, framework and build method
- Functions, workers, cron jobs and platform services in use
- Database, storage and approximate transfer volume
- Domains, integrations and required environments
- Maintenance window and desired operations after the move
Plan the target platform, application and operations together
After migration, WZ-IT can continue operating the deployment platform, the application or its underlying infrastructure within the appropriate scope. Where the target is still unclear, the path starts with a separate PaaS Exit Review.
Coolify managed hosting
Have Coolify operated with Git integration, deployments, databases, backups, updates and monitoring.

Frequently asked questions about PaaS and cloud exit
Vercel, Heroku, Coolify, Railway, Render, Fly.io, Netlify, data and operations
PaaS and cloud-exit migration starts at €1,990 excluding VAT. The starting price is not a blanket fixed scope. The binding price depends on applications, platform capabilities, data, required code changes, target environment and cutover requirements.
Next.js supports self-hosting in principle. Before migration, we assess the Vercel-specific functions, edge runtimes, image optimisation, caches, cron jobs, integrations and environment variables the application actually uses. Those capabilities must be reproduced or adapted on the target platform.
No. Coolify is one possible platform for builds, deployments and application services. Hetzner is one possible infrastructure provider. Coolify can run on German, European or customer-owned infrastructure; Docker, Kubernetes or operations without an additional PaaS layer are also possible.
Yes, those environments can be rebuilt on the target platform. Branches, builds, domains, variables, data access and release processes are planned separately. The exact scope depends on the current workflow and required isolation.
Yes, when they are part of the agreed scope. Databases, volumes, uploads and object storage are moved separately from the application and then validated. Export path, data volume, write rate and permitted downtime determine the approach.
That depends on data volume, write activity, DNS, dependencies and target architecture. After the technical assessment, we plan the test deployment, final data sync, cutover and rollback checkpoint. Very low or zero downtime can increase effort substantially.
Yes. The target process can continue to use Git pushes, automated builds and controlled deployments. We can also separate staging and production and add reviews, approvals, health checks and rollback.
Yes. Depending on the target, we can operate Linux servers, Coolify or another platform, backups, monitoring and updates. Software maintenance, CVE assessment, releases and technical development of the application are agreed as a separate application scope.

“WZ-IT's advice on our Azure migration was technically sound and completely non-binding right from the intro call - we took away a great deal.”
Migrations with measurable business impact
Cloud exit, Proxmox and sovereign operations with concrete results instead of architecture slides.
“I recently worked with Timo and the WZ-IT team, and honestly, it turned out to be one of the best tech decisions I have made for my business. Right from the start, Timo took the time to walk me through every step in a simple and calm way. No matter how many questions I had, he never rushed me. The results speak for themselves. With WZ-IT, we reduced our monthly expenses from $1,300 down to $250. This was a huge win for us.”

“Communication with WZ-IT was open, friendly and professional from the very beginning. Mr. Wevelsiep and Mr. Zins responded to every one of our questions patiently, promptly and respectfully, and contributed their own suggestions and good ideas on how to modernize our server infrastructure and adapt it even better to our needs. Throughout, WZ-IT consistently kept our need for data sovereignty and GDPR compliance in mind. Even short-notice adjustments and change requests from our side were implemented quickly and patiently and integrated consistently into the overall concept. From planning to the final handover, every step was documented transparently and comprehensively - so if a provider change should ever become necessary, the documentation would let us onboard a successor into our infrastructure very quickly. We are extremely satisfied with WZ-IT and hope to continue working together for a long time.”
