• Open and upgrade Service Management data files on the server the first time you open the application.
• Open and upgrade Purchasing and Inventory data files on the server console, not through Remote Desktop.
• Upgrading data on a workstation sets DSNs incorrectly and causes data access errors.

    Purchasing and Inventory modules on older versions

• If using Purchasing or Inventory in version 8.3.x or 9.1.x, apply Software Alert 05-M or 05-P before upgrading to 9.4.1. Contact Sage Support for getting these updates.
