@atgalvez08 Always remember to link the corresponding issue (#1191) to inform others that you're handling this migration.

Typically, migrations consist of two commits:

1. Pre-commit fixes (before migrating to the target version)
2. The migration itself

Sometimes only one commit is needed. Also, are you familiar with https://github.com/OCA/oca-port? I recommend checking out OCA's YouTube playlists for helpful videos about this tool.

@atgalvez08 Please review the standard contribution procedure. Based on the PR title, this appears to be a migration, but the commit history hasn't been preserved according to OCA conventions.

Refer to the migration guide here: https://github.com/OCA/maintainer-tools/wiki/Migration-to-version-17.0. The wiki contains specific pages for each version migration.

Please address my comments and ping me when it's ready. I would be glad to review it.

You need to review the general procedure to contribute. From the title of the PR I'm assuming it's a migration but you didn't preserve commit history according to OCA conventions. Check out https://github.com/OCA/maintainer-tools/wiki/Migration-to-version-17.0. In that wiki there is one page for each version migration.

This PR has been superseded by #1648, which redoes the migration using oca-port to preserve commit history.
