Kumtor Gets Communicating With Evolv

A complex global Exchange 5.5 to Exchange 2003 migration project required industry leading skills from evolv networks for the successful migration in Central Asia.

Kumtor Operating Company is a wholly owned subsidiary of Centerra Gold, based in the Kyrgyz Republic. It is the largest gold mine operated in Central Asia by a Western-based company, having produced more than 8.4 million ounces of gold between 1997 and the end of 2011. As one of the largest companies in the Kyrgyz republic, with thousands of local and international employees, it is heavily reliant on communications infrastructure.

During 2006, Kumtor approached evolv networks to consolidate its messaging infrastructure into the global MS Exchange infrastructure. Since the two organisations [Centerra and Kumtor] functioned as separate entities, consolidating the metadata and information between their two directories was a complex and intricate procedure. Over a period of two-and-a-half months, evolv networks built a synchronisation infrastructure and migrated hundreds of users over more than eight sites in the Kyrgyz republic.

“The solution combined complex scripting and policy-driven management systems to provide a seamless integration during the co-existence phase. Downtime was therefore non-existent and end-user experience was not impacted negatively during the migration. In fact, most users felt the system was not only faster, but provided them with access to the global Centerra directory of information,” says Francois Conradie, Technical Director, evolv networks.

Eight MS Exchange 5.5 Servers hosting several databases was consolidated into three Exchange 2003 clusters. This could be achieved by using a more thin method of connectivity [RPC over HTTPS] provided in the Exchange stack. The surface complexity was therefore reduced and administration simplified.
