 After you upgrade the operator, you might need to upgrade your Redis Enterprise clusters, depending on the Redis software version bundled with the operator. For detailed information about the upgrade process, see [Redis Enterprise for Kubernetes upgrade documentation](https://redis.io/docs/latest/operate/kubernetes/upgrade/).

+If your databases use user-defined modules (custom non-bundled modules), you must take additional steps during the upgrade process. See [Upgrade with user-defined modules]({{< relref "/operate/kubernetes/upgrade/upgrade-redis-cluster#user-defined-modules" >}}) for details.

+## Add user-defined modules (optional)

+If you plan to create databases that use user-defined modules (custom non-bundled modules), you must add them to the REC custom resource before creating the databases.

+See [User-defined modules]({{< relref "/operate/kubernetes/re-databases/modules#user-defined-modules" >}}) for detailed instructions on adding and configuring custom modules.

 ## Create a Redis Enterprise Database (REDB)
 
 You can create multiple databases within the same namespace as your REC or in other namespaces.

 {{<warning>}}Redis Enterprise for Kubernetes 7.2.4-2 introduces a new limitation. You cannot recover or upgrade your cluster if there are databases with old module versions or manually uploaded modules. See the [Redis Enterprise Software 7.2.4 known limitations]({{< relref "/operate/rs/release-notes/rs-7-2-4-releases/rs-7-2-4-52#cluster-recovery-with-manually-uploaded-modules" >}}) for more details.{{</warning>}}

+If your cluster uses user-defined modules, the recovery process doesn't block on module validation errors (such as URL or credential issues). The cluster can recover successfully, and you can resolve any module configuration issues after recovery is complete. See [User-defined modules]({{< relref "/operate/kubernetes/re-databases/modules#user-defined-modules" >}}) for more information.

 ## Prerequisites
 
 - For cluster recovery, the cluster must be [deployed with persistence]({{< relref "/operate/kubernetes/recommendations/persistent-volumes" >}}).
