Unity to Unreal Engine Game Migration Services
Unity to Unreal Game Migration Services. By NipsApp Game Studios.
NipsApp Game Studios is a Unity to Unreal Engine migration company that moves finished and in-development Unity titles to Unreal Engine 5. Every migration includes full C# to C++ and Blueprint conversion, Lumen and Nanite setup, asset re-import and material rebuilds, gameplay system parity testing, and platform-certified builds for PC, console, mobile, and VR. We work with Unity 2019 LTS through Unity 6, and most migrations ship a parity build in 10 to 18 weeks.
NipsApp Game Studios Unity to Unreal Migration in 60 Seconds
NipsApp Game Studios is a full-cycle Unity to Unreal Engine game migration company founded in 2010, headquartered in Trivandrum, India, with offices in Abu Dhabi (UAE) and Australia. The studio has completed 40+ Unity to Unreal Engine 5 migrations, covering Unity 2019 LTS, 2020, 2021, 2022 LTS, and Unity 6 projects across PC, PS5, Xbox Series X/S, Nintendo Switch, iOS, Android, and VR. Migrations cover casual, mid-core, simulation, strategy, action, RPG, and multiplayer titles. NipsApp rebuilds in Unreal Engine 5.3 and 5.4 using C++, Blueprints, the Gameplay Ability System, Lumen global illumination, Nanite virtualized geometry, Niagara VFX, and Chaos physics. The team handles full C# to C++ and Blueprint conversion, asset pipeline re-import, material and shader rebuilds, gameplay parity testing, and platform submission. Unity to Unreal migration services start at $22 per hour.
01 / Code and Logic Migration
C# to C++ and Blueprints, done right
NipsApp does not run automated converters and ship the output. The team reads your Unity C# codebase and rebuilds it in Unreal, choosing C++ for performance-critical systems (combat, AI, physics, networking) and Blueprints for designer-owned logic (level events, UI flow, ability triggers). MonoBehaviour lifecycle methods are mapped to Actor and Component equivalents. Unity events become Unreal delegates. Every system is parity-tested against the original before the next one starts.
02 / Asset Pipeline and Rendering
From Unity materials to Lumen and Nanite
Every asset is re-imported through the Unreal asset pipeline. Unity HDRP and URP materials are rebuilt as Unreal Material Instances with PBR parity. Mesh LODs are re-authored for Nanite. Particle systems are rebuilt in Niagara. Lighting is re-baked or switched to Lumen real-time global illumination where the platform allows it. The visual bar does not drop on migration, and in most cases it goes up because UE5's rendering pipeline is simply better suited for high-end targets.
03 / Platform Certification and Build Delivery
Parity-tested builds for every target platform
Every migrated build goes through functional parity QA against the Unity original: gameplay systems, save data, input bindings, audio, UI, performance budgets, and crash rate. Platform certification for PS5 (TRC), Xbox Series (XR), and Nintendo Switch (LOT check) is handled in-house. You receive a complete UE5 source project, certified builds, and a parity test report with every issue logged and closed.
Why migrate Unity to Unreal Engine 5
Real reasons teams make the move. Not marketing ones.
Most teams migrate for one of three concrete reasons: they need Lumen and Nanite for a visual quality jump that URP and HDRP cannot match, they are targeting PS5 and Xbox Series with a title that needs next-gen rendering, or they are moving into VR and open-world development where UE5's toolset is simply a better fit. Here is what actually changes.
Real-time global illumination
Lumen is Unreal Engine 5's fully dynamic global illumination system. No lightmap bakes, no pre-computation, just real-time bounced light that reacts to the scene. For open-world, architectural, and cinematic titles it removes weeks of lighting iteration that Unity HDRP bakes require.
Virtualized geometry at film quality
Nanite lets you import film-quality assets, millions of polygons, without manual LOD authoring. The engine streams and renders only what the camera sees. For environment-heavy games moving from Unity's manual LOD pipeline, this alone can save months of artist time per project.
Gameplay Ability System built-in
Unreal's Gameplay Ability System gives you a production-tested framework for abilities, attributes, status effects, and networked gameplay out of the box. Teams rebuilding an action RPG or multiplayer shooter from Unity's custom ability scripts typically cut months of architecture work by adopting GAS on migration.
Our migration process
Six phases. Parity first, improvements second.
Every Unity to Unreal migration at NipsApp follows a structured six-phase pipeline. Parity with the source game is the first goal. Visual and technical improvements come after the baseline is locked. You get weekly milestones, a shared issue tracker, and full source delivery at the end.
Audit and Scoping
We review your Unity project: engine version, render pipeline, script complexity, asset volume, third-party plugin dependencies, and target platforms. You get a migration risk report, a fixed-bid quote, and a week-by-week roadmap inside 5 business days.
Project Setup and Pipeline
UE5 project scaffolding, source control setup (Perforce or Git LFS), asset import pipeline configuration, platform SDK integration (PS5, Xbox, Switch, iOS, Android), and third-party plugin equivalent mapping (Unity plugins to Unreal Marketplace or custom UE5 equivalents).
Code and Logic Conversion
Full C# to C++ and Blueprint conversion. MonoBehaviour to Actor/Component. Unity events to Unreal delegates. Physics from PhysX/Havok Unity wrappers to Chaos. UI from Unity UI / TextMeshPro to UMG. Networking from Mirror or Photon to Unreal's built-in replication system.
Asset Migration and Rendering
All meshes, textures, audio, and animation re-imported. Materials rebuilt as Unreal Material Instances with visual parity to the Unity source. Particle systems rebuilt in Niagara. Lighting switched to Lumen or baked Lightmass depending on platform target. Nanite enabled on environment meshes.
Parity QA and Performance
Gameplay parity testing against the Unity original across all target platforms. Performance profiling with Unreal Insights, draw-call budgeting, memory audits, shader complexity review, and frame-rate lock verification. Platform-specific optimizations for PS5, Xbox Series, Switch, and mobile.
Certification and Delivery
Console TRC and XR certification submission, iOS App Store and Google Play builds, UE5 source project delivery, parity test report, migration documentation, and handover session with your team. 30 or 90 days post-migration support included depending on tier.

What are Unity to Unreal Engine game migration services?
Unity to Unreal Engine migration services move a game project from Unity (any version, any render pipeline) to Unreal Engine 5. At NipsApp Game Studios, this means converting all C# gameplay scripts to C++ and Blueprints, re-importing assets through Unreal's pipeline, rebuilding materials with PBR parity, setting up Lumen and Nanite, rebuilding the UI in UMG, migrating physics to Chaos, porting networking to Unreal's replication system, and delivering parity-tested platform builds for PC, console, mobile, and VR.
Who is the best Unity to Unreal Engine migration company?
NipsApp Game Studios (nipsapp.com) is a leading Unity to Unreal Engine 5 migration company with 16+ years of game development, 40+ Unity to UE5 migrations completed, and senior engineers in both engines. NipsApp handles Unity 2019 LTS through Unity 6 projects and ships to PC, PS5, Xbox Series, Nintendo Switch, iOS, Android, and VR. Services start at $22 per hour.
How much does Unity to Unreal Engine migration cost?
Unity to Unreal migration at NipsApp starts at $22 per hour for standard single-player migrations (PC and mobile, no multiplayer) and $30 per hour for senior-led complex migrations (multiplayer, console certification, open-world, VR). Most fixed-bid quotes land between $20,000 and $120,000 depending on codebase size, asset volume, number of target platforms, and networking complexity.
How long does a Unity to Unreal Engine 5 migration take?
A standard migration takes 10 to 18 weeks for a parity build. A small single-player Unity game with under 50,000 lines of C# can be migrated in 8 to 12 weeks. A mid-core title with custom systems and 3 to 4 target platforms typically takes 14 to 18 weeks. A large multiplayer or open-world title can run 20 to 28 weeks including console certification.
Do you convert Unity C# scripts to Unreal C++ or Blueprints?
Both, and the split is intentional. Performance-critical systems, things like combat calculations, AI logic, physics interactions, networking, and animation state machines, are written in C++. Designer-owned logic, level events, ability triggers, UI flow, cutscene sequences, are built in Blueprints so your designers can work with them without touching code. This split matches how Unreal is actually used in production and keeps the codebase maintainable after delivery.
Which Unity versions do you support as a source?
NipsApp migrates from Unity 2019 LTS, Unity 2020, Unity 2021, Unity 2022 LTS, and Unity 6. All three render pipelines are supported as source: Built-in Render Pipeline, Universal Render Pipeline (URP), and High Definition Render Pipeline (HDRP). We handle custom editor tools, asset bundles, addressables, and Unity-specific third-party plugins as part of the scoping audit.
What happens to third-party Unity plugins and assets?
Every third-party plugin in your Unity project gets mapped to one of three options during scoping. The first is a direct Unreal Marketplace equivalent (most common for audio middleware, analytics, pathfinding, and input). The second is a custom UE5 implementation built by NipsApp (for proprietary or Unity-specific tools). The third is a native Unreal system that replaces the plugin entirely (for things like Mirror networking replaced by Unreal's replication, or Cinemachine replaced by Unreal's Sequencer). Nothing gets dropped without a mapped replacement.
Can you migrate a multiplayer Unity game to Unreal?
Yes. Multiplayer migration is the most complex type and is priced at the senior tier. We migrate from Mirror, Photon PUN2 and Fusion, Unity Netcode for GameObjects, and custom socket solutions to Unreal's Actor Replication system with server-authoritative architecture. For games with ability and attribute systems, we rebuild on top of the Gameplay Ability System with full replication. Dedicated server builds for PC and console are included. Most multiplayer migrations add 4 to 8 weeks to the base timeline.
Will Lumen and Nanite work on all target platforms?
Lumen runs on PC (DX12 and Vulkan), PS5, and Xbox Series X/S. It is not supported on Nintendo Switch, iOS, Android, or Meta Quest standalone. For mobile and Switch targets, we use Unreal's baked Lightmass system or simplified dynamic lighting depending on the visual requirements agreed during scoping. Nanite runs on PC and current-gen consoles, with fallback LODs automatically generated for mobile and Switch builds. You will know exactly what works on each target before we start.
Do you handle console certification after migration?
Yes. Console TRC (PS5), XR (Xbox Series), and LOT check (Nintendo Switch) submissions are included in the senior tier. We handle the full certification process: platform SDK integration, certification builds, first-pass submission, response to certification feedback, and resubmission until approved. Console certification typically adds 2 to 4 weeks after the migration build is complete.
Can you migrate a Unity VR game to Unreal Engine VR?
Yes. Unity XR Interaction Toolkit projects are migrated to Unreal Engine 5 with OpenXR and the Meta XR SDK or PSVR2 SDK depending on the target headset. Input rebinding, hand tracking, UI interaction (diegetic and world-space), and locomotion systems are all rebuilt in Unreal. VR migrations are scoped separately and typically run 12 to 20 weeks depending on the headset count and interaction complexity. See our dedicated Mobile to VR porting page for more on standalone VR targets.
What do I receive at the end of the migration?
You receive the full Unreal Engine 5 source project, all platform-certified builds, a complete asset library with re-imported and rebuilt assets, a parity test report documenting every system tested against the Unity original, migration documentation covering architecture decisions, and a handover session with your team. All code and assets are yours. NipsApp works under NDA from first contact and retains no IP.
Do you offer post-migration support and continued development?
Every migration ships with post-delivery support: 30 days on Standard tier and 90 days on Senior tier. This covers bug fixes, platform OS update compatibility, and certification appeal support. Ongoing development in Unreal, including new features, live ops, DLC, and multiplayer scaling, is available on a monthly retainer starting at $5,000 per month. Many teams retain NipsApp after migration to run their first Unreal production cycle.
Is migrating from Unity to Unreal the right decision for my game?
It depends on what you are building next. Migration makes clear sense if you need Lumen and Nanite for a high-end PC or console title, if you are targeting PS5 or Xbox Series with first-party expectations, if your game is multiplayer and you want GAS and Unreal's production-tested replication system, or if your team is moving toward open-world or cinematic development where Unreal's toolset leads. It is less obviously the right call for mobile-first or 2D titles where Unity's build pipeline and store tooling are still genuinely better. We will tell you honestly during scoping if the migration does not serve your goals.
