Case Study: a expense management client achieves faster, accurate Elasticsearch upgrades with Softjourn

a expense management client achieves 0.02% search difference with Softjourn, Inc.

Softjourn, Inc. worked with an expense management client that needed to upgrade its Elasticsearch system from version 2.3.4 to 7.9. The client's challenge was ensuring the upgrade would not impact the high-quality search results for its users, as making such a large jump between versions posed significant risks including performance issues and potential errors.

Softjourn developed a custom comparison tool and Java microservices to evaluate and ensure the accuracy of the new search version. The result was a successful upgrade hosted on AWS, with users experiencing faster searches and a negligible difference of less than 1% in results. The client can also reuse the custom tool for future upgrades, saving time and money.
