Telekom Srbija a.d. is a communications company founded in 1997 following the restructuring of the public telecommunications enterprise PTT Communications Srbija. The company provisions fixed and mobile telephony, internet, satellite communications, data transfer services, and line leasing in Serbia. Telekom Srbija has international operations in Bosnia, Herzegovina, and Montenegro. The Serbian government owns 78.11% of the company’s shares after transferring 6.94% of shares to Telekom Srbija’s employees and 14.95% of shares to Serbia’s citizens in May 2012.
“We upgraded to Oracle E-Business Suite Release 12.1 because we wanted to benefit of the numerous enhancements of that release. It is mandatory to be technologically up-to-date, and we are also looking ahead to our migration to Oracle Fusion Middleware technology that will further reduce costs, improve the quality of key processes, and maximize IT efficiency. Our cooperation with Oracle Consulting was flawless and very enriching for our IT team,” said Danijela Pavlović, head of human resources support section, Telekom Srbija.
Telekom Srbija upgraded to Oracle E-Business Suite Release 12.1 in two months using internal resources as well as support from Oracle Consulting. During that period, the organization conducted two test migrations. The migration of productive systems had to be performed over a weekend.
“We expected to need a much larger budget and at least six months to complete the upgrade. But we realized that the help of Oracle Consulting and thorough planning, neither the upgrade costs nor the timeframe would be an issue,” Pavlović added.
In terms of lessons learned, Telekom Serbia notes that organizations should take certain steps to ensure a successful upgrade on time and within budget. For example, organizations should design a detailed project plan that defines all steps, their order, and necessary resources; ensure that the entire technology stack runs on the latest patches; document all existing customizations; and determine which customizations should be replaced with out-of-the-box features.
