## How It Works
|
||||||
|
|
||||||
|
### Overview
|
||||||
|
|
||||||
|
The script performs a **step-by-step migration** between each major version. For example, to migrate from 14.0 to 17.0, it executes:
|
||||||
|
|
||||||
|
```
|
||||||
|
14.0 → 15.0 → 16.0 → 17.0
|
||||||
|
```
|
||||||
|
|
||||||
|
### Process Steps
|
||||||
|
|
||||||
|
1. **Initial Checks**
|
||||||
|
- Argument validation
|
||||||
|
- Required command verification (`docker`, `compose`, `sudo`, `rsync`)
|
||||||
|
- Source database and filestore existence check
|
||||||
|
|
||||||
|
2. **Environment Preparation**
|
||||||
|
- Creation of a fresh Odoo database in the target version (for module comparison)
|
||||||
|
- Copy of the source database to a working database
|
||||||
|
- Filestore copy
|
||||||
|
|
||||||
|
3. **Database Preparation** (`scripts/prepare_db.sh`)
|
||||||
|
- Neutralization: disable mail servers and cron jobs
|
||||||
|
- Detection of installed modules missing in the target version
|
||||||
|
- View state verification
|
||||||
|
- User confirmation prompt
|
||||||
|
|
||||||
|
4. **Migration Loop** (for each intermediate version)
|
||||||
|
- `pre_upgrade.sh`: version-specific SQL fixes before migration
|
||||||
|
- `upgrade.sh`: OpenUpgrade execution via Docker
|
||||||
|
- `post_upgrade.sh`: fixes after migration
|
||||||
|
|
||||||
|
5. **Finalization** (`scripts/finalize_db.sh`)
|
||||||
|
- Obsolete sequence removal
|
||||||
|
- Modified website template reset
|
||||||
|
- Compiled asset cache purge
|
||||||
|
- Duplicated view fixes
|
||||||
|
- Obsolete module cleanup
|
||||||
|
- Final update with `-u all`
|
||||||
|
|
||||||

## Usage
|
## Usage
|
||||||
### Before migration
|
|
||||||
|
|
||||||
- [ ] import the origin database to migrate on local computer
|
### Before Migration
|
||||||
- [ ] Uninstall all known useless Odoo add-ons. Warning: do not uninstall add-ons for which the disappearance in the finale version is managed by Open Upgrade scrips.
|
|
||||||
- [ ] Unsure all the add-ons are migrated in the final Odoo version
|
|
||||||
- [ ] (optional) De-active all the website views
|
|
||||||
|
|
||||||
### Local Migration process
|
1. **Import the source database** to your local machine
|
||||||
|
|
||||||
- [ ] launch the origin database `ORIGIN_DATABASE_NAME` with original version of Odoo, with odoo service `ORIGIN_SERVICE`
|
2. **Clean up the source database** (recommended)
|
||||||
- [ ] launch the following command:
|
- Uninstall unnecessary modules
|
||||||
|
- Do NOT uninstall modules handled by OpenUpgrade
|
||||||
|
|
||||||
|
3. **Check module availability**
|
||||||
|
- Ensure all custom modules are ported to the target version
|
||||||
|
|
||||||
|
4. **Start the Docker environment**
|
||||||
|
```bash
|
||||||
|
# Start the PostgreSQL container
|
||||||
|
compose up -d postgres
|
||||||
|
|
||||||
|
# Verify only one postgres container is running
|
||||||
|
docker ps | grep postgres
|
||||||
|
```
|
||||||
|
|
||||||
|
### Running the Migration
|
||||||
|
|
||||||
```bash
|
```bash
|
||||||
./upgrade.sh {ORIGIN_VERSION} {DESTINATION_VERSION} {ORIGIN_DATABASE_NAME} {ORIGIN_SERVICE}
|
./upgrade.sh <source_version> <target_version> <database_name> <source_service>
|
||||||
```
|
```
|
||||||
ex: ./upgrade.sh 14 16 elabore_20241208 odoo14
|
|
||||||
|
|
||||||
- [ ] Inspect the list of add-ons identified as missing in the final Odoo docker image:
|
**Parameters:**
|
||||||
- if you want to uninstall some of them:
|
| Parameter | Description | Example |
|
||||||
- STOP the process (N)
|
|-----------|-------------|---------|
|
||||||
- uninstall the concernet add-ons manually
|
| `source_version` | Source Odoo version (without .0) | `14` |
|
||||||
- launch the migration script again
|
| `target_version` | Target Odoo version (without .0) | `17` |
|
||||||
- if the list suits you, show can go on (Y)!
|
| `database_name` | Database name | `my_prod_db` |
|
||||||
|
| `source_service` | Source Docker Compose service | `odoo14` |
|
||||||
|
|
||||||
The migration process should run all the middle-migrations until the last one without action needed from you.
|
**Example:**
|
||||||
|
```bash
|
||||||
|
./upgrade.sh 14 17 elabore_20241208 odoo14
|
||||||
|
```
|
||||||
|
|
||||||
### Deploy migrated base
|
### During Migration
|
||||||
|
|
||||||
- [ ] Retrieve the migrated database (vps odoo dump)
|
The script will prompt for confirmation at two points:
|
||||||
- [ ] Copy the database on the concerned VPS
|
|
||||||
- [ ] vps odoo restore
|
|
||||||
|
|
||||||
|
1. **Missing modules list**: installed modules that don't exist in the target version
|
||||||
|
- `Y`: continue (modules will be marked for removal)
|
||||||
|
- `N`: abort to manually uninstall certain modules
|
||||||
|
|
||||||
## Manage the add-ons to uninstall
|
2. **View state**: verification of potentially problematic views
|
||||||
|
- `Y`: continue
|
||||||
|
- `N`: abort to manually fix issues
|
||||||
|
|
||||||
The migration script will manage the uninstall of Odoo add-ons:
|
### After Migration
|
||||||
- add-ons we want to uninstall, whatever the reasons
|
|
||||||
- add-ons to uninstall because they do not exist in the final Odoo docker image
|
|
||||||
|
|
||||||
At the beginning of the process, the script compare the list of add-ons installed in the origin database, and the list of add-ons available in the finlal Odoo docker image.
|
1. **Review logs** to detect any non-blocking errors
|
||||||
|
|
||||||
The whole list of add-ons to uninstall is displayed, and needs a confirmation before starting the migration.
|
2. **Test the migrated database** locally
|
||||||
|
|
||||||
## Customize the migration scripts
|
3. **Deploy to production**
|
||||||
|
```bash
|
||||||
|
# Export the migrated database
|
||||||
|
vps odoo dump db_migrated.zip
|
||||||
|
|
||||||
FEATURE COMING SOON...
|
# On the production server
|
||||||
|
vps odoo restore db_migrated.zip
|
||||||
|
```
|
||||||
|
|
||||||
|
## Customization
|
||||||
|
|
||||||
## Manage migration issues
|
### Version Scripts
|
||||||
|
|
||||||
As the migration process is performed on a copy of the orginal database, the process can be restarted without limits.
|
Each `versions/X.0/` directory contains three scripts you can customize:
|
||||||
|
|
||||||
Some Odoo migration errors won't stop the migration process, then be attentive to the errors in the logs.
|
#### `pre_upgrade.sh`
|
||||||
|
Executed **before** OpenUpgrade. Use it to:
|
||||||
|
- Add missing columns expected by OpenUpgrade
|
||||||
|
- Fix incompatible data
|
||||||
|
- Remove problematic records
|
||||||
|
|
||||||
|
```bash
|
||||||
|
#!/bin/bash
|
||||||
|
set -euo pipefail
|
||||||
|
|
||||||
|
echo "Prepare migration to 15.0..."
|
||||||
|
|
||||||
|
copy_database ou14 ou15 ou15
|
||||||
|
|
||||||
|
PRE_MIGRATE_SQL=$(cat <<'EOF'
|
||||||
|
-- Example: remove a problematic module
|
||||||
|
DELETE FROM ir_module_module WHERE name = 'obsolete_module';
|
||||||
|
EOF
|
||||||
|
)
|
||||||
|
query_postgres_container "$PRE_MIGRATE_SQL" ou15
|
||||||
|
|
||||||
|
copy_filestore ou14 ou14 ou15 ou15
|
||||||
|
|
||||||
|
echo "Ready for migration to 15.0!"
|
||||||
|
```
|
||||||
|
|
||||||
|
#### `upgrade.sh`
|
||||||
|
Runs OpenUpgrade migration scripts.
|
||||||
|
|
||||||
|
#### `post_upgrade.sh`
|
||||||
|
Executed **after** OpenUpgrade. Use it to:
|
||||||
|
- Fix incorrectly migrated data
|
||||||
|
- Remove orphan records
|
||||||
|
- Update system parameters
|
||||||
|
|
||||||
|
```bash
|
||||||
|
#!/bin/bash
|
||||||
|
set -euo pipefail
|
||||||
|
|
||||||
|
echo "Post migration to 15.0..."
|
||||||
|
|
||||||
|
POST_MIGRATE_SQL=$(cat <<'EOF'
|
||||||
|
-- Example: fix a configuration value
|
||||||
|
UPDATE ir_config_parameter
|
||||||
|
SET value = 'new_value'
|
||||||
|
WHERE key = 'my_key';
|
||||||
|
EOF
|
||||||
|
)
|
||||||
|
query_postgres_container "$POST_MIGRATE_SQL" ou15
|
||||||
|
```
|
||||||
|
|
||||||
|
### Available Functions
|
||||||
|
|
||||||
|
Version scripts have access to functions defined in `lib/common.sh`:
|
||||||
|
|
||||||
|
| Function | Description |
|
||||||
|
|----------|-------------|
|
||||||
|
| `query_postgres_container "$SQL" "$DB"` | Execute an SQL query |
|
||||||
|
| `copy_database $from $to_service $to_db` | Copy a PostgreSQL database |
|
||||||
|
| `copy_filestore $from_svc $from_db $to_svc $to_db` | Copy a filestore |
|
||||||
|
| `log_info`, `log_warn`, `log_error` | Logging functions |
|
||||||
|
| `log_step "title"` | Display a section header |
|
||||||
|
|
||||||
|
### Adding a New Version
|
||||||
|
|
||||||
|
To add support for a new version (e.g., 19.0):
|
||||||
|
|
||||||
|
```bash
|
||||||
|
mkdir versions/19.0
|
||||||
|
cp versions/18.0/*.sh versions/19.0/
|
||||||
|
|
||||||
|
# Edit the scripts to:
|
||||||
|
# - Change references from ou18 → ou19
|
||||||
|
# - Change the port from -p 8018:8069 → -p 8019:8069
|
||||||
|
# - Add SQL fixes specific to this migration
|
||||||
|
```
|
||||||
|
|
||||||
|
## Troubleshooting
|
||||||
|
|
||||||
|
### Common Issues
|
||||||
|
|
||||||
|
#### "No running PostgreSQL container found"
|
||||||
|
```bash
|
||||||
|
# Check active containers
|
||||||
|
docker ps | grep postgres
|
||||||
|
|
||||||
|
# Start the container if needed
|
||||||
|
compose up -d postgres
|
||||||
|
```
|
||||||
|
|
||||||
|
#### "Multiple PostgreSQL containers found"
|
||||||
|
Stop the extra PostgreSQL containers:
|
||||||
|
```bash
|
||||||
|
docker stop <container_name_to_stop>
|
||||||
|
```
|
||||||
|
|
||||||
|
#### "Database not found"
|
||||||
|
The source database must exist in PostgreSQL:
|
||||||
|
```bash
|
||||||
|
# List databases
|
||||||
|
docker exec -u 70 <postgres_container> psql -l
|
||||||
|
|
||||||
|
# Import a database if needed
|
||||||
|
docker exec -u 70 <postgres_container> pgm restore <file.zip>
|
||||||
|
```
|
||||||
|
|
||||||
|
#### "Filestore not found"
|
||||||
|
The filestore must be present at `/srv/datastore/data/<service>/var/lib/odoo/filestore/<database>/`
|
||||||
|
|
||||||
|
### Restarting After an Error
|
||||||
|
|
||||||
|
The script works on a **copy** of the original database. You can restart as many times as needed:
|
||||||
|
|
||||||
|
```bash
|
||||||
|
# Simply restart - the copy will be recreated
|
||||||
|
./upgrade.sh 14 17 my_database odoo14
|
||||||
|
```
|
||||||
|
|
||||||
|
### Viewing Detailed Logs
|
||||||
|
|
||||||
|
Odoo/OpenUpgrade logs are displayed in real-time. For a problematic migration:
|
||||||
|
|
||||||
|
1. Note the version where the error occurs
|
||||||
|
2. Check the logs to identify the problematic module/table
|
||||||
|
3. Add a fix in the `pre_upgrade.sh` for that version
|
||||||
|
4. Restart the migration
