Migration tool from company-managed (formerly classic) to team-managed (formerly next-gen) project and vice-versa

Problem Definition

At the moment, moving from company-managed (formerly classic) project to team-managed (formerly next-gen) requires a manual effort of creating the target team-managed (formerly next-gen) project and performing a bulk update.

Suggested Solution

Allow a feature to easily migrate from company-managed (formerly classic) projects to team-managed (formerly next-gen) projects without losing fields' data and vice versa.
