# Migration guide
Migration is a module for migrating database schema between different version of project [Harbor](https://github.com/vmware/harbor)
This module is for those machine running Harbor's old version, such as 0.1.0. If your Harbor' version is up to date, please ignore this module.
**WARNING!!** You must backup your data before migrating
###Installation
- step 1: change `db_username`, `db_password`, `db_port`, `db_name` in migration.cfg
- step 2: build image from dockerfile
```
cd harbor-migration
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```
- step 4: rebuild newest Harbor images and restart service
```
docker-compose build && docker-compose up -d
```
You may change `/data/database` to the mysql volumes path you set in docker-compose.yml.
