= Update the infinispan Subsystem

The JBoss Server Migration Tool makes the following updates to the *infinispan* subsystem configuration to better match the {server-target-productName} default configurations.

* Adds `concurrent` cache to the `web` cache container, which is present in the {server-target-productName} default configuration.

By default, the tool automatically updates any *infinispan* subsystem configuration to include these changes.
If you prefer, you can set the `subsystem.infinispan.update.skip` environment property to `true` to skip automatic update of *infinispan* subsystem configurations.

Upon successful migration of a *infinispan* subsystem configuration, you should see the following message in the console:

[source,options="nowrap"]
----
 INFO  Subsystem infinispan updated.
