UE4.18-to-UE5.7 Migration

@itswahabahmad

As an experienced game developer specializing in Unreal Engine, I am more than qualified to undertake this UE4.18-to-UE5.7 migration project. My extensive experience in dealing with both the core game code and third-party plugins in UE ensures that I can navigate your heavily modified codebase, resolve any build errors and deprecated API calls effectively while ensuring your custom engine tweaks remain intact. Your emphasis on the networking layer and custom input system is perfectly envisioned as these areas can be quite challenging during an engine migration process. Over my 6+ years of work, I've tackled multiple multiplayer projects and resolved intricate C++ issues concerning networked gameplay smoothly. Moreover, with my profound AWS DevOps knowledge, you can have peace of mind knowing that not only will I deliver a clean and functional UE 5.7 project but also ensure it operates optimally in a robust infrastructure. Let's team up to migrate your game seamlessly to UE 5.7 for an immersive gaming experience like never before!

The migration to UE 5.7 will be done with the necessary updates in C++ so that your project runs without errors on UE 5.7. The multiplayer layer will be well migrated to UE 5.7. Looking forward to your contact.

I’ve handled engine migrations like this before, including projects with custom engine forks and multiplayer-heavy C++ code, so I understand this is not a simple version bump. My approach would be to first diff your UE 4.18 engine modifications against Epic’s source, then re-apply or refactor only what’s still relevant in the UE 5.7 architecture. I’ll update deprecated APIs across the game code and third-party plugins, with extra focus on networking and input, since both have changed significantly between 4.x and 5.x. I’ll work iteratively: get the project compiling, then clean up runtime issues until Play-In-Editor is stable with multiple clients. The goal is a clean UE 5.7 project that opens and runs without crashes, so you can take over Blueprint and asset updates confidently. You’ll receive either a Git branch or a packaged project that builds in Visual Studio on Windows, along with a short migration report explaining what was changed, which engine tweaks were re-implemented, and any remaining limitations or recommended follow-ups. I’m comfortable working directly in engine source, untangling legacy multiplayer code, and dealing with large version gaps. If you can share details on the scope of your engine modifications and plugins, I can get started quickly.

Hi, I’m a senior developer with experience working on Unreal Engine, including custom engine tweaks and multiplayer systems. I’d love to help bring your game’s C++ codebase forward from UE 4.18 to UE 5.7. I’ll update the engine-level changes you made in 4.18 to ensure they apply cleanly in UE 5.7, resolve any build errors, and address deprecated API calls. I’ll pay special attention to the networking layer and custom input system to ensure smooth functionality in the new version. By the end of the project, I’ll deliver a working UE 5.7 project that builds and runs without errors or crashes. I’ll also provide a brief migration report that highlights the fixes applied and any follow-up items. Let me know if you'd like to discuss the details further. I’m excited to help you move this project forward!

I am confident I can deliver exactly what you’re looking for by adhering strictly to your stated requirements and scope. The need for a clean migration of all engine-level changes from UE 4.18 to UE 5.7, especially ensuring the networking layer and custom input system remain stable, demands precise and error-free execution. My approach centers on careful code review, aligning strictly with the defined scope, and systematically resolving build errors and deprecated APIs without making assumptions. Reliability and thoroughness in handling edge cases will be prioritized throughout the process. Although I am new to Freelancer, I bring strong real-world experience and have completed many projects off this platform. I’d be happy to discuss the details whenever you’re ready.
