Progress OpenEdge Migration of Application Server from Classic to PASOE for Enhanced Performance and Efficiency

Empowering Business Growth through Technology Transformation and Seamless Migration.

The Client

Our client stands as a historic and esteemed international auction house, established in 1793, renowned for its exceptional auctions featuring fine art, antiques, motor cars, and jewellery. Based in London, England, the company enjoys a prestigious reputation in the global art market. With a legacy spanning centuries, it continues to attract artists, writers, and collectors, showcasing their expertise and influence in the art and antique industry.

The Challenges

  1. Technical Debt Challenges: The Auctioneer technology stack was burdened with significant technical debt, which hindered the maintenance and improvement processes.

  2. Maintenance Complexity: The accumulation of technical debt made routine maintenance challenging and, in some cases, nearly impossible, creating operational bottlenecks.

  3. End-of-Life Components: Many components in the existing stack approached end-of-life status or had already been retired, posing a substantial risk to ongoing support and functionality.

  4. Modernization Hurdles: The presence of extensive technical debt hampered the modernization efforts of the application, making it difficult to adapt to evolving industry standards and user demands.

  5. Critical Support Risk: The overall technical debt represented a critical support risk, necessitating urgent attention to avoid potential system failures and ensure a seamless modernization process.

The Objective

Auctioneer product aimed to embark on the journey of:

  • Better performance of the existing Product

  • Enhancing the customer experience

  • Update the technology stack to achieve the above goals.

The Solution

  • The JK Tech expert team of developers moved the application from a classic environment to Progress Application Server for OpenEdge (PASOE).

  • We have adjusted the configuration of the PASOE based on the client’s existing architecture.

  • After providing multiple approaches for the PASOE and instance creations, both JK Tech and the client agreed upon the creation of a single PASOE with multiple Webapps.

  • Certain changes were made to the application’s code to ensure it functions properly after the migration.

Issues resolved in Upgrade execution-

  1. Security and Script Execution:

    • Issue: A Perl script couldn’t run due to spring security restrictions in PASOE.

    • Resolution: An HTTPS certificate was implemented on PASOE and configured with Apache 2.4, allowing secure script execution.

  2. Configuration Issues and File Mismatch:

    • Issue: Configuration files were conflicting, and JavaScript file names in the database didn’t match those on the server.

    • Resolution: Conflicts in configuration files were resolved, and the mismatched JavaScript file names were synchronized, ensuring a smooth migration process.


  • We have performed unit testing on every component that has been changed to ensure the functionality is maintained.

  • The test result and report have been submitted to the client.
