Migration Ledger - find AND FIX what an Unreal upgrade silently broke
An Unreal Engine 5 plugin from Core Systems Asset Factory. Made with Unreal Engine. Paid.
Migration Ledger - find AND FIX what an Unreal upgrade silently broke is an Unreal Engine 5 plugin for Unreal Engine, paid.
Its title or description names Unreal Engine 5. Its store page states that commercial use is permitted; the exact licence terms are on the store page.
It does not just tell you. It writes the fix. Unreal already has a supported, declarative way to say "this old name now means that new name" — Core Redirects. Epic ships 817 of them in BaseEngine.ini. This is not a clever trick; it is the vendor's own migration mechanism, used the way it is meant to be used.
Migration Ledger reads the deprecations out of the engine on your machine and generates the redirects your project needs, into a separate, reviewable CoreRedirects.ini.
On a stock UE 5.8 install that is 1,446 redirects. [CoreRedirects] +ClassRedirects=(OldName="IForceFeedbackSystem",NewName="IInputInterface"); deprecated 5.1 +StructRedirects=(OldName="FRHITextureSRVCreateInfo",NewName="FRHITextureSRVCreateDesc"); deprecated 5.3 +FunctionRedirects=(OldName="ConvertToRawMesh",NewName="FStaticMeshOperations::ConvertToRawMesh"); deprecated 5.5 It does not write into your DefaultEngine.ini for you.
You read it, then you paste it. Undoing it is deleting the lines — that is the entire rollback. -Fix also corrects a.uplugin whose EngineVersion would make the engine skip loading it, and reads the file back to confirm the change actually landed. Your C++ is never rewritten.
