PURPOSE
this script will start in DRY MODE by default - see --GO parameter
- Migrate assignments for Gitea-Issues after a Gitea2Gitea-Migration
- issues must have the same ID on both systems
- users must have the same NAME on both systems
- example
- OLD: https://oldgitea.example.com/my_organisation/my_repository
- NEW: https://newgitea.example.com/my_organisation/my_repository
- Typical Workflow
1. migrate your repository from your OLD Gitea instance to your NEW one
2. use this script to migrate the assignments
