Sentree K.K., based in Tokyo, Japan, provides 24 x 7 x 365 technology consulting, project management and a blend of on-site and remote support to its clients, whose technology needs are typically mission-critical.

A key Sentree K.K. client required an upgrade of their data center-hosted Zimbra server that was end-of-life.  The client required a short downtime window for the actual migration, repeated testing prior to the migration, and full rollback capabilities in the event something went horribly wrong.

Mission Critical Email architected a migration plan to meet Sentree K.K.’s client’s needs, and executed the plan in collaboration with Sentree K.K. engineering staff.

Said Jason Wik, Sentree K.K.’s Managing Director: “Mark Stone’s technical expertise around Zimbra and virtualization enabled us to provide a very cost-effective, low-risk migration path for our consultancy client, whose reliance on email is truly mission-critical. Mark’s sensitivity to our client’s risk aversion helped us craft a testing program that enabled us to better manage our client’s expectations and lower their migration risk at the same time.”
