Migrating from a _Single Instance_ to a _Cluster_
|
|
==================================================
|
|
|
|
{% hint 'info' %}
|
|
Before migrating from a _Single Instance_ to a Cluster,
|
|
please read about
|
|
[**Single Instance vs. Cluster**](architecture-single-instance-vs-cluster.html)
|
|
{% endhint %}
|
|
|
|
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_](programs-arangodump.html)
|
|
and [_arangorestore_](programs-arangorestore.html).
|
|
|
|
{% hint 'warning' %}
|
|
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.
|
|
|
|
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_.
