Migrating from a Single Instance to a Cluster

Before migrating from a Single Instance to a Cluster, please make sure to read the Single Instance vs. Cluster page.

If you have developed your application using a Single Instance and you would like to use a Cluster now, before upgrading your production system please test your application with the Cluster first.

To migrate from a Single Instance to a Cluster you will need to take a backup from the Single Instance and restore it into the Cluster with the tools arangodump and arangorestore.

If both your Single Instance and Cluster are running on the same machine, they should have distinct data directories. It is not possible to start a Cluster on the data directory of a Single Instance.
