# Migration guide

Migration is a module for migrating database schema between different version of project [Harbor](https://github.com/vmware/harbor)
|
|

###Installation
|
|
- step 1:
|
|
|
|
```
|
|
cd migration
|
|
```
|
|
- step 2: change `db_username`, `db_password`, `db_port`, `db_name` in migration.cfg
|
|
- step 3: build image from dockerfile
|
|
|
|
```
|
|
docker build -t migrate-tool .
|
|
```

###Migrate Step
|
|
- step 1: stop and remove Harbor service
|
|
|
|
```
|
|
docker-compose down
|
|
```
|
|
- step 2: create backup file in `/path/to/backup`
|
|
|
|
```
|
|
docker run -ti --rm -v /data/database:/var/lib/mysql -v /path/to/backup:/harbor-migration/backup migrate-tool backup

|
|
- step 3: perform database schema upgrade
|
|
|
|
```docker run -ti --rm -v /data/database:/var/lib/mysql migrate-tool up head```
|
|
|
|
|

|
|
|
|
```
