Rehearse editor upgrades, protect save data, validate serialization migrations, measure Addressables impact, and trace prefab changes.Treat upgrades as measured migrations. Upgrade & Data Migration Toolkit combines five complete tools that protect project structure, serialized data, content delivery, prefabs, and player saves before a release changes them.**Complete tools included**- Upgrade Impact Lab- Save Compatibility Lab- Serialization Migration Guard- Addressables Patch Impact- Prefab Override GPSRehearse a target Editor on a disposable clone, compare serialized schemas, replay real saves, measure Addressables patch impact, and trace prefab overrides back to their source.The tools report evidence and migration risk. They do not modify the source project, generate migrations automatically, or guarantee every runtime path.PRODUCT TYPE- Bundle of five complete upgrade, serialization, save, Addressables, and prefab tools.REQUIREMENTS- Unity 2022.3 or newer.- Git is optional and used only for source revision and clone evidence.- Save Compatibility Lab version 1 targets JsonUtility-compatible JSON.INCLUDED TOOLS- Upgrade Impact Lab- Save Compatibility Lab- Serialization Migration Guard- Addressables Patch Impact- Prefab Override GPSSHARED CAPABILITIES- Before/after snapshots and deterministic comparisons.- Local reports with evidence and next actions.- CI-compatible checks where supported by the component tool.IMPORTANT- Upgrade rehearsals cover configured checks, not every device or gameplay path.- Save and serialization checks cover declared roots, snapshots, corpora, and migrations.OpenAI image generation was used to create the original toolkit icon. Codex assisted with layout and copy drafting. The included tool functionality is not AI-generated; every component list, technical claim, price, and final image was manually reviewed.
