# Update QlikView Application Scripts

The Update QlikView Application Scripts step retrieves all QlikView applications from the migration plan and updates their load scripts within the Qlik Cloud tenant.

## Prerequisite steps

* `Import QlikView Applications`

## Step details

* Retrieval method:  
  Applications are located using the custom description metadata generated during the import process.

* Backup:  
  Before any script changes are applied, a backup of the original script is saved in the App Backups folder inside the project directory.

* Script updates:

  * Data connection strings are updated using the definitions provided in the Data Connections sheet of the plan.
  * Search and replace operations defined in the Search Replace sheet are executed line-by-line.
  * Common static or deprecated QlikView-specific values are automatically replaced with their Qlik Cloud-compatible alternatives.

## Note

This step provides a streamlined mechanism to modernize and adapt QlikView load scripts for Qlik Cloud compatibility. Script updates are driven by both configuration sheets and static QlikView-specific substitutions to reduce manual remediation.
