Rehearse a Unity upgrade on a disposable clone. Compile, test, build, and compare before the target editor ever touches your real project.Verified working in Unity 2022 and Unity 6.A Unity upgrade should be a measured rehearsal, not the first time a new editor opens your real project. Upgrade Impact Lab creates a disposable clone, records a baseline, runs the target editor against the clone, and reports exactly what changed or failed.What it helps you doSelect a current editor and an installed target editor.Clone the project outside the working tree and keep the real project untouched.Import, clean-compile, run tests, and optionally build in the target editor.Compare packages, project settings, files, compiler output, tests, and build results semantically.Separate expected upgrade churn from actionable breakage.Export deterministic JSON, Markdown, and self-contained HTML evidence.Repeat the same rehearsal in CI with meaningful exit codes.Use it before moving a production project to a new LTS or Unity 6 release, when package compatibility is uncertain, or when the cost of opening the real project too early is high.The target editor never opens your real project. Only the disposable clone is upgraded. A successful rehearsal proves the configured checks passed; it cannot prove every runtime path on every device.Read the complete documentation.PRODUCT TYPEEditor-only Unity upgrade rehearsal and semantic comparison tool.REQUIREMENTSCurrent editor: Unity 2022.3 or newer.Target editor: any installed Unity editor that Unity Hub can start in batch mode.Windows, macOS, and Linux editors are supported.Enough free disk space for a disposable project clone and optional build output.KEY FEATURESDisposable clone with explicit safety checks; the target editor never opens the source project.Baseline and target-editor phases for import, clean compile, tests, and optional player build.Semantic package, settings, project file, compiler, test, and build comparison.Reuses completed phases when their inputs still match.Clear findings with evidence, affected area, and suggested next action.JSON, Markdown, and self-contained HTML reports with SHA-256 evidence.Batch mode and CI exit codes.IMPORTANT LIMITSA rehearsal covers the checks you enable; it does not exercise every game path or device.Package behavior can still differ on platforms not built or tested during the rehearsal.The clone requires disk space and the selected editors must already be installed.The tool does not modify the source project, install editors, or resolve upgrade findings automatically.Full documentation.AI-assisted image generation was used for the package icon artwork, and AI-assisted drafting was used for marketing copy and documentation formatting. All technical claims were sourced from the package, and the code, functionality, layouts, exports, and final text were manually reviewed and verified.
