# Introduction
This PR refactors the way we previously manually handled the upgrade
command `versionTo` and `versionFrom` values to be replaced by a
programmatic inferring using the `APP_VERSION` env variable. It raises
new invariant edge cases that are covered by new tests and so on
Please keep in mind that an upgrade will run agnostically of any `patch`
semver value as it should be done only when releasing a `major/minor`
version update

## Testing in local
In order to test in local we have to define an `APP_VERSION` value in
`packages/twenty-server/.env` following semver ( or not 🙃 )
