+## Upgrade databases
 
 After the cluster is upgraded, you can upgrade your databases.
 
+### Upgrade REDB
+
 To upgrade your REDB, specify your new database version in the `spec.redisVersion` field in the REDB or REAADB custom resources. Supported database versions for operator versions include "7.2", "7.4", "8.0", and "8.2" (note this value is a string).  
 
+### Upgrade REAADB
+
 For Active-Active databases, the `redis.Version` change only needs to be applied on one participating cluster and will automatically propagate to all other participating clusters. All participating clusters must be running operator version 8.0.2-2 or later.
 
 If your REAADB uses supported modules, keep the existing `moduleList` version numbers unchanged when upgrading `redisVersion`. The database will automatically use the module versions that are bundled with the new Redis version, regardless of what versions are specified in `moduleList`. After the upgrade is complete, you can optionally change the old version numbers from `moduleList`, but this change has no functional impact.
