-## Migrating to v4
-
-From version `v4` the project has been moved under [@kiegroup](https://github.com/kiegroup) organization. During this migration we changed some things that you should be aware of. I'll try to summarize them in the following table:
-
-> **NOTE**: these changes did not affect the tool features.
-
-|             | **v4 (after migration)** | v3 or older (before migration) |
-|-------------|--------------------------|--------------------------------|
-| Owner       | kiegroup                 | lampajr                        |
-| Repository  | git-backporting          | backporting                    |
-| NPM package | @kie/git-backporting     | @lampajr/bper                  |
-| CLI tool    | git-backporting          | bper                           |

-So everytime you would use older version keep in mind that these changes are madnatory to make the tool working.
-
-> **NOTE**: Versions `v3.1.1` and `v4.0.0` offer identical features; the only distinction lies in the project's renaming and organization movement.
