# Server --> Control --> JTA Migration Config.

Tasks Related Topics

## Overview

On the Server—>Control—>JTA Migration Config tab in the Administration Console, you can limit the choices of the servers to use as a Transaction Recovery Service backup for a server in a cluster. For example, only certain servers in your cluster may have access to the transaction log files for a server. When you select target servers in the Server—>Control—>JTA Migration Config tab, you can limit the list of destination servers available on the Server—>Control—>Migrate JTA tab.

The Server—>Control—>JTA Migration Config tab shows a list of Available servers (servers in the cluster) and a list of Chosen server. If you do not specify a list of chosen servers, you can migrate the Transaction Recovery Service to any server in the cluster.

Notes: You can only migrate the Transaction Recovery Service from one server in a cluster to another server in the same cluster that can access the transaction log of the failed server.

If you specify a list of chosen servers, you must include the current server in the list or you will not be able to migrate the service back to the server after transactions are recovered.
