# Update change types
<a name="ct-updates"></a>

AMS provides Update change types to update resources that were created with Create change types. The Update change types must be matched version-to-version with the Create change type originally used to provision the resource.

We recommend keeping a record of the change type ID and version that you use when provisioning a resource to make it easy to update it.
