This guide covers upgrade and migration to version 1.9.0. This guide only covers migration from v1.7.x and later to the current version. If you are upgrading from an earlier version, refer to the migration guide in the `release-1.7.0` branch to upgrade to v1.7.x first, then follow this guide to perform the migration to this version.
When upgrading an existing Harbor 1.7.x instance to a newer version, you might need to migrate the data in your database and the settings in `harbor.cfg`.
Since the migration might alter the database schema and the settings of `harbor.cfg`, you should **always** back up your data before any migration.
**NOTES:**
- Again, you must back up your data before any data migration.
- Since v1.8.0, the configuration of Harbor has changed to a `.yml` file. If you are upgrading from 1.7.x, the migrator will transform the configuration file from `harbor.cfg` to `harbor.yml`. The command will be a little different to perform this migration, so make sure you follow the steps below.
- In version 1.9.0, some containers are started by `non-root`. This does not pose problems if you are upgrading an officially released version of Harbor, but if you have deployed a customized instance of Harbor, you might encounter permission issues.
- In previous releases, user roles took precedence over group roles in a project. In this version, user roles and group roles are combined so that the user has whichever set of permissions is highest. This might cause the roles of certain users to change during upgrade.
- With the introduction of storage and artifact quotas in version 1.9.0, migration from 1.7.x and 1.8.x might take a few minutes. This is because the `core` walks through all blobs in the registry and populates the database with information about the layers and artifacts in projects.
- With the introduction of storage and artifact quotas in version 1.9.0, replication between version 1.9.0 and a previous version of Harbor does not work. You must upgrade all Harbor nodes to 1.9.0 if you have configured replication between them.
Alternatively, if you are using an offline installer package you can load it from the image tarball included in the offline installer package. Replace [version] with the release version of Harbor (e.g. v1.5.0) in the below command:
5. If you are current version is v1.7.x or earlier, i.e. migrate config file from `harbor.cfg` to `harbor.yml`.
**NOTE:** You can find the ${harbor_yml} in the extracted installer you got in step `3`, after the migration the file `harbor.yml`
in that path will be updated with the values from ${harbor_cfg}
```sh
docker run -it --rm -v ${harbor_cfg}:/harbor-migration/harbor-cfg/harbor.yml -v ${harbor_yml}:/harbor-migration/harbor-cfg-out/harbor.yml goharbor/harbor-migrator:[tag] --cfg up
```
Otherwise, If your version is 1.8.x or higher, just upgrade the `harbor.yml` file.
```sh
docker run -it --rm -v ${harbor_yml}:/harbor-migration/harbor-cfg/harbor.yml goharbor/harbor-migrator:[tag] --cfg up
```
**NOTE:** The schema upgrade and data migration of the database is performed by core when Harbor starts, if the migration fails, please check the log of core to debug.
6. Under the directory `./harbor`, run the `./install.sh` script to install the new Harbor instance. If you choose to install Harbor with components such as Notary, Clair, and chartmuseum, refer to [Installation & Configuration Guide](../docs/installation_guide.md) for more information.
