# Migration
|
|
|
|
|
|
|
|
|
|
Run this script when doing database migration. Example :
|
|
|
|
|
|
|
|
|
|
```bash
|
2026-02-13 03:46:27 -05:00
|
|
|
source ./.venv.odoo15.0_python3.8.20/bin/activate && cat ./script/odoo/migration/fix_migration_odoo140_to_odoo150.py | ./odoo15.0/odoo/odoo-bin shell -d DATABASE
|
2025-10-31 01:10:54 -04:00
|
|
|
```
|
|
|
|
|
|
|
|

[ADD] migration: see and repair the website COW views
A copy-on-write view freezes the module view it came from; the module moves
on and the upgrade dies hours later on a missing anchor. These tools
predict, snapshot, diff, neutralize and reset them. The migration screen
gains the real state of each step, replay from any of them, and statistics.
--- FR ---
Une vue copy-on-write fige la vue de module dont elle vient ; le module
évolue et la mise à niveau meurt des heures plus tard sur un point
d'ancrage absent. Ces outils les prévoient, photographient, comparent,
neutralisent et réinitialisent. L'écran de migration gagne l'état réel de
chaque étape, la reprise depuis n'importe laquelle, et des statistiques.

## Module lists to uninstall
|
|
|
|
|
|
|
|
|
|
Before a version bump, the migration uninstalls the modules listed in
|
|
|
|
|
`uninstall_module_list_odoo<from>_to_odoo<to>.txt`. Two locations are read, the
|
|
|
|
|
private one first, and the results are merged (duplicates dropped):
|
|
|
|
|
|
|
|
|
|
1. `private/odoo/migration/<database>/uninstall_module_list_odooXX0_to_odooYY0.txt`
|
|
|
|
|
— specific to ONE database, not versioned. Which modules must be dropped
|
|
|
|
|
depends on the data, so this is where nearly every entry belongs.
|
|
|
|
|
2. `script/odoo/migration/uninstall_module_list_odooXX0_to_odooYY0.txt`
|
|
|
|
|
— shared defaults, versioned, valid for every database.
|
|
|
|
|
|
|
|
|
|
Syntax: one module per line, with a justification after `#`. Commas and several
|
|
|
|
|
names per line are accepted; blank lines and full-line comments are ignored.
|
|
|
|
|
A module without a stated reason is flagged at runtime: removing a module is a
|
|
|
|
|
decision someone must be able to review later.
|
|
|
|
|
|
|
|
|
|
```
|
|
|
|
|
queue_job # blocks 12->13, trigger queue_job_notify
|
|
|
|
|
mgmtsystem_hazard # not ported to 13.0
|
|
|
|
|
web_syncer # dropped upstream
|
|
|
|
|
```
