Microsoft SQL Server 2012 Upgrade Advisor is a legacy tool used to analyze older instances of SQL Server (such as 2005, 2008, and 2008 R2) to identify breaking changes, deprecated features, and syntax changes before upgrading to SQL Server 2012. It generates detailed reports highlighting issues you must fix either before or after the upgrade process. 1. Prerequisites and Installation
Before running the Upgrade Advisor, you must install the proper dependencies, which often cause installation errors if missed:
Required Frameworks: Ensure Microsoft .NET Framework 4.0 is installed on the machine.
Missing Prerequisite Bug: A common roadblock is a missing scripting dependency. You should download and install the Microsoft SQL Server 2012 Transact-SQL ScriptDom component (x86 or x64) before launching the installer.
Installer: Launch the installer (SQLUA.msi) downloaded from the official Microsoft SQL Server 2012 Feature Pack. 2. Step-by-Step Usage
The application is split into two primary wizards: Analysis Wizard and Report Viewer. Phase A: Run the Upgrade Advisor Analysis Wizard Upgrade SQL Server – Microsoft Learn
