 Transitioning between versions is often as simple as executing a new binary or container, but there are times when updates are more complex.
 For example, releases that include changes to datastore can require that users update to specific versions and perform a series of actions in order to update while avoiding any downtime.

 ## Migrating from SpiceDB to SpiceDB

     Migrating data at the underlying database level is not recommended and impossible in some cases. Using tools like `pg_dump`/`pg_restore` will break SpiceDB MVCC. Additionally, if you are migrating to a SpiceDB with a different datastore type (e.g. Postgres -> CockroachDB), you ***must*** use the SpiceDB APIs (`exportBulk`/`importBulk` or `zed backup`) to backup and restore.
