# `mix mailglass.upgrade.v0_2`
[🔗](https://github.com/szTheory/mailglass/blob/v2.7.0/lib/mix/tasks/mailglass.upgrade.v0_2.ex#L10)

Transitional codemod that upgrades adopter code from raw `Swoosh.Email`
usage to native `Mailglass.Message` setters.

Use this task as one step in the canonical `0.x -> 1.0` migration path, not
as the whole compatibility contract by itself. The authoritative guide lives
at `guides/upgrading-to-v1_0.md`.

## Options

  * `--apply` - actually apply the changes to the files. Default is a dry-run.
