This post is intended for users who are ready to upgrade their old projects to 3.0.0, to address and give feedback on issues encountered while migrating Prefab.
Due to a complete refactoring of the Prefab system in 3.0, there was a risk that some parameters would be lost when migrating Prefab data from lower versions. Therefore, we provide a separate upgrade method for the migration module to facilitate quick iteration.
