When planning a migration from QlikView to Qlik Sense with the goal of improvement, a data architect must consider a holistic set of criteria. The business use case is paramount as it defines the requirements and success criteria. Analyzing the source data architecture is fundamental to ensure data is accessed efficiently and correctly. The load script and data model are the core technical components of the QlikView application that must be evaluated for migration, optimization, or complete redesign. Finally, a strategy for QlikView archival is a crucial part of the overall migration plan to manage the transition and decommissioning of the old environment.

A. Application theme and storytelling are Qlik Sense-specific user interface features, not primary architectural planning criteria for a data architect.

B. Compatibility is too vague as a criterion, and while user sessions are important for capacity planning, they are secondary to the core data architecture.

D. This option incorrectly includes UI elements (application theme) and uses the less appropriate term IT use case instead of the business-driven business use case.

1. Qlik Sense Deployment Framework: The official framework outlines the phases for successful Qlik Sense implementation, which applies to migration scenarios. The "Analyze" phase emphasizes understanding business requirements (business use case), inventorying existing applications (including their load script and data model), and assessing data sources (source data architecture). The "Govern" aspect of the framework implicitly covers the lifecycle management of old applications (QlikView archival).

2. QlikView to Qlik Sense Modernization Documentation: Qlik's official guidance on modernization repeatedly highlights the need to analyze the existing QlikView applications. This analysis focuses on the complexity of the script and data model to determine the migration path (e.g., reuse, re-engineer, or retire). This directly supports the inclusion of load script and data model as key criteria.

3. QlikView Converter Documentation: The QlikView Converter is a tool to assist in migration. Its documentation details which components, such as the load script and variables, can be converted. This underscores the necessity of analyzing the script as a primary step in the migration plan.
