About the Project
The project required a team to be established across many functions including service delivery, client support, platform support, network, security and product management. Two parallel streams were kicked off initially. The first was focused on sourcing the new co-located space within a dedicated suite that would comply with the company’s ISO27001 and SSAE 16 accreditation, whilst the second performed an audit of all the systems and services which would be impacted. The audit revealed several gaps in current service procedures which needed to be filled before the migration could take place. The gaps identified by the audit were resolved and detailed analysis was undertaken to establish an accurate set of dependencies which would inform the day by day migration plan. It was imperative that the plans took into account the 100% service availability target.
The migration took place over 6 weeks, and was split into 5 phases. This approach enabled both sites to be run in parallel whilst the migration took place, with services effectively split across the two locales until the final network migration had been completed.
Phase 1 – Build of co-location space, core infrastucture (power, HVAC etc), and core network
Phase 2 – Pilot move to prove the logistics, refine the outage timings and identify improvements to the process
Phase 3 – Servers running email and web based scanning services that could be load balanced across other data-centres to maintain cluster capacity
Phase 4 – Servers and SAN controlling the web administration portal
Phase 5 – Network migration
A ticketing system was used to help track the migration of each system. This covered the lifecycle of every movement, from system shutdown through to re-commissioning.
