# Configuring System Update Sets

Configure your instance with tracked app installations or merge update sets into a single update set.

-   **[Enable application installation tracking through an update set](https://raw.githubusercontent.com/ServiceNow/ServiceNowDocs/australia/markdown/australia/application-development/system-update-sets/enable-application-installation-tracking-through-update-set.md)**  
You can add specific applications or versions as an app installation and configure to track them in an update set.
-   **[Overwrite customizations during an upgrade](https://raw.githubusercontent.com/ServiceNow/ServiceNowDocs/australia/markdown/australia/application-development/system-update-sets/t_OverwriteCustomizsDuringUpgrades.md)**  
Specify which customized objects you want to replace during the next upgrade. By default, the upgrade process skips changes to customized objects.
-   **[Merge update sets](https://raw.githubusercontent.com/ServiceNow/ServiceNowDocs/australia/markdown/australia/application-development/system-update-sets/t_MergeUpdateSets.md)**  
Merge multiple update sets into a single update set.
-   **[Set up the source instance for an update set](https://raw.githubusercontent.com/ServiceNow/ServiceNowDocs/australia/markdown/australia/application-development/system-update-sets/setting-source-for-update-set.md)**  
Set up the source instance for an update set.
-   **[Save an update set as a local XML file](https://raw.githubusercontent.com/ServiceNow/ServiceNowDocs/australia/markdown/australia/application-development/system-update-sets/t_SaveAnUpdateSetAsAnXMLFile.md)**  
Administrators can export an update set as an XML file to save a specific version of an application or set of changes.
-   **[Update set transfers](https://raw.githubusercontent.com/ServiceNow/ServiceNowDocs/australia/markdown/australia/application-development/system-update-sets/update-set-transfers.md)**  
When an update set is completed, you can transfer it between instances to move customizations from development, through testing, and into production.
-   **[Grant access to the update set picker](https://raw.githubusercontent.com/ServiceNow/ServiceNowDocs/australia/markdown/australia/application-development/system-update-sets/t_GrantAccessToTheUpdateSetPicker.md)**  
Enable specific roles to access the update set picker.
