# How to move from Unity Game Server Hosting to Gameye

A CTO-oriented migration framework for moving from Unity-hosted dedicated servers to Gameye orchestration with low operational risk.

Unity Game Server Hosting can be a strong option for Unity-native stacks, but teams often outgrow one-vendor constraints as infrastructure, concurrency, and region requirements become more complex.

## Why teams migrate

Studios usually look for:

- Engine independence across multiple projects.

- More control over providers, regions, and deployment policy.

- Better cost visibility and optimization levers at scale.

- Less strategic lock-in between engine and hosting decisions.

## What changes and what stays the same

Most core gameplay architecture can stay intact:

- Authoritative server logic.

- Existing networking models.

- Matchmaking rules and queue behavior.

- Client flow for connecting to server endpoints.

What typically changes is orchestration:

- Dedicated server builds are packaged as Docker images.

- Backend or matchmaker calls the Gameye Session API.

- Capacity and placement are managed by Gameye policies across regions/providers.

## Practical migration plan

### 1. Validate dedicated server readiness

Confirm your Linux headless server build is portable, configurable via environment variables, and observable through logs.

### 2. Containerize releases

Package server builds into versioned images and push via CI/CD so each release can be scheduled consistently.

### 3. Swap orchestration calls

Keep matchmaking logic intact while replacing host allocation calls with Gameye session allocation calls.

### 4. Roll out gradually

Validate functionality, latency, and cost baselines, then migrate by region, game mode, or weighted routing percentages.

## Team ownership model

- Backend/platform: image pipeline, API integration, observability wiring.

- Gameplay/networking: lifecycle readiness behavior and runtime validation.

- LiveOps/production: rollout sequencing, KPI tracking, incident readiness.

## CTO outcomes

Migration reduces strategic lock-in and improves control over latency, cost, and provider-mix policy while keeping rollout reversible and measurable.

## Frequently asked questions

**Do I need to rewrite my game server code to move to Gameye?**
No. Your authoritative server logic, networking model, and matchmaking rules stay unchanged. The migration is at the orchestration layer — packaging your server as a Docker image and replacing allocation calls with the Gameye Session API.

**Does Gameye require a Unity plugin or SDK in my server?**
No. Gameye requires no SDK, plugin, or code changes in your game server binary. Your server starts, listens on a port, and accepts connections. Gameye manages everything externally.

**How long does migration from Unity Game Server Hosting take?**
Studios typically complete the migration in under two weeks with parallel testing. The main steps: containerise your server build, swap the allocation API call, and roll out region by region. [Step-by-step checklist](https://gameye.com/unity-multiplay-to-gameye/).

**Can I run both platforms in parallel during migration?**
Yes. Most studios run Gameye alongside their existing provider during migration, routing a percentage of traffic to Gameye for validation before cutting over fully. This keeps the rollout reversible and measurable.
