odoo migration v13 to v16: change content of manifest file

Question

In the context of odoo migration of my custom modules from v13 to v16. In my src/user/custom_module, I want to adapt the content of the manifest file to the new v16-requirements. Originnaly, i have a manifest file in v13 (__manifest__.py) which contains assets.xml in the data entry ('data': [ ...]) And i have created a new manifest file which fits the requirements for v16 (v16__manifest__.py): it contains assets directly as entry ('assets': [ ...]) and does not use assets.xml amymore.

Using the standard migration scripts architecture (migrations/13.0.2/pre-migrate.py), i manage to change the name of the 2 manifests files, so that:

__manifest__.py get renamed to v13__manifest__.py
v16__manifest__.py get renamed to __manifest__.py

# content of migrations/13.0.2/pre-migrate.py

def swap_mf_version():
    # code ok: rename manifest files accordingly using pathlib

# This function invoked only if system already have 13.0.0 version installed
def migrate(cr, version):
    swap_mf_version()

The code get executed and does the job : the 2 files get renamed but it triggers a reload of the module ("python code updated, autoreload activated "). Here the Traceback:

KeyboardInterrupt

I have already tried to handle this using a pre_init_hook but it won t be triggered...

How could I do this renaming, as migration step, before launching the module ?
