Imperial College London

The Client founded in 1907 has grown to an organisation with approximately 13,000 students and an estate spread across multiple buildings in and outside of the London M25 borders.

The existing Lenel access control system is has approximately 13,000 card holders and 2000 card readers with bespoke data base integration to various ICT modules.    


As a Lenel VAR, Controlled Ltd was commissioned to carry out a major software upgrade from version 5.12.100 to 6.4.500 TU1.1. Under the management of the Imperial College ICT department.

Our technical services department planned and managed the Lenel Access control system upgrade transition which involved migration from MS Windows 2003/ Oracle 10Gr2 to MS Windows VMware 2008 Oracle 11Gr1.


A project with strictly no room for error and zero downtime, multiple simulated server switch overs ensured complete project delivery with zero disruption to day to day card holders.
