Upgrading and rolling back #

The Starburst ODBC driver v3 series is described in the following pages:

• Overview
• Installation
• Configuration
• This page — Upgrading and rolling back

This page provides instructions for upgrading from the Starburst ODBC driver v2 series to the v3 series, and describes how to roll back from the v3 series to the v2 series.

Upgrading #

The Starburst driver v3 series is a drop-in replacement for the v2 series. The upgrade process is seamless for most users.

Upgrade process #

When you install the Starburst driver v3 series on a system with an installed v2 series driver:

1. The v3 series installer automatically removes the v2 series driver.
2. The v3 series is installed in the same location as the v2 series driver.
3. Existing DSNs from the v2 series driver remain accessible in the ODBC Data Sources Administrator window.

DSN compatibility #

• Viewing DSNs: You can view and use existing v2 series DSNs without making any changes.
• Modifying DSNs: If you modify and save a v2 series DSN, the installer upgrades it to the v3 series configuration format.
• One-way upgrade: Once you save a DSN with v3 series settings, you cannot open it with the v2 series driver without losing configuration settings. See the rollback process for more information.

Application compatibility #

The Starburst driver v3 series has been tested with the following applications:

• Power BI
• Tableau
• SQL Server (via linked server)
• Excel

If you are using other applications and encounter any issues, contact Starburst Support for assistance.

Rolling back #

If you need to roll back from the Starburst ODBC driver v3 series to the v2 series:

1. Restore DSN configurations:
   • Open a command prompt as an administrator.
   • Navigate to the driver installation directory (the default is C:\Program Files\Starburst ODBC Driver).
   • Execute starburst-dsn-restore-x64.exe.
   • This restores any DSNs that were upgraded to v3 series back to the v2 series format.
2. Uninstall the v3 series
   • Use the Windows Add or remove programs feature to uninstall the Starburst ODBC driver v3 series.
3. Install version 2:
   • Install the v2 series driver using the files on the ODBC driver v2 series page.
