Background:

A leading travel booking site that negotiates deep discounts from its travel suppliers to help travelers book unsold airline seats, hotel rooms, rental cars, cruises and vacation packages has very strict downtime requirements during Go-Live. Estuate developed a radical new approach specifically for the travel booking site using multiple iterations for deliverables to complete Oracle 12 upgrade on schedule and on budget with unique upgrade process leveraging a U.S./India team.

The travel booking site finance team engaged with Estuate to upgrade the existing Oracle Application release 11.5.10 to Oracle Apps release 12.1.3. The impetus for the upgrade was that the current Oracle Apps version (11.5.10.2) has moved from active support on November 2010 to extended support mode. Additionally, they asked Estuate to migrate the Oracle instance to Red Hat Enterprise Linux 5.x from Solaris 9.

The Opportunity:

  • Move the travel booking site’s Financial Application to the latest supported version.
  • Major modules included for upgrade are GL, AP and AR.
  • Retrofit previous customizations
