## 2.5 to 2.6 upgrade
> Upgrade Best Practices

> There are [important changes to the upgrade process](/ee/upgrade) that, if not correctly followed, can have impact on the availability of applications running on the Swarm during upgrades. These constraints impact any upgrades coming from any version before `18.09` to version `18.09` or greater. See [Cluster Upgrade Best Practices](/ee/upgrade.md#cluster-upgrade-best-practices) for more details. Additionally, to ensure high availability during the DTR upgrade, you can also drain the DTR replicas and move their workloads to updated workers. To do this, you can join new workers as DTR replicas to your existing cluster and then remove the old replicas. See [docker/dtr join](/reference/dtr/2.6/cli/join) and [docker/dtr remove](/reference/dtr/2.6/cli/remove) for command options and details.
When upgrading from `2.5` to `2.6`, the system will run a `metadatastoremigration` job after a successful upgrade. This involves migrating the blob links for your images which is necessary for online garbage collection. With `2.6`, you can log in to the DTR web interface and navigate to **System > Job Logs** to check the status of the `metadatastoremigration` job. See [Audit Jobs via the Web Interface](../manage-jobs/audit-jobs-via-ui/) for more details.

* Web Interface
* Users with read-only permissions to a repository can edit the repository README but their changes will not be saved. Only repository admins should have the ability to [edit the description](../admin/manage-users/permission-levels/#team-permission-levels) of a repository. (docker/dhe-deploy #9677)
* Poll mirroring for Docker plugins such as `docker/imagefs` is currently broken. (docker/dhe-deploy #9490)
