Migrating the install base information for existing cases

concept brazil Updated Sep 10, 2026 1 min read install-base-existing-cases.md

Your customer service agents can use the case form on the CSM Agent Workspace to add an install base item to an existing case.

To populate existing cases with the install base information, agents can use the following sample script:

JavaScript

var installBaseMigrationUtil = new sn_install_base.InstallBaseMigrationUtils(); installBaseMigrationUtil.populateInstallBaseOnCases();

The migration script populates cases with the install base information, only if the case is associated with the install base item. To associate a case to an install base item, see Associate multiple install base items to a case.

# Migrating the install base information for existing cases

Your customer service agents can use the case form on the CSM Agent Workspace to add an install base item to an existing case.

To populate existing cases with the install base information, agents can use the following sample script:

```
var installBaseMigrationUtil = new sn_install_base.InstallBaseMigrationUtils(); 
installBaseMigrationUtil.populateInstallBaseOnCases(); 
```

The migration script populates cases with the install base information, only if the case is associated with the install base item. To associate a case to an install base item, see [Associate multiple install base items to a case](https://raw.githubusercontent.com/ServiceNow/ServiceNowDocs/brazil/markdown/customer-service-management/associate-multiple-install-base-items-case.md).
