Four week datacentre migration: doing it the Agile way

Working Agile with giffgaff teams, Pelicam provided project guidance on appropriate, risk-balanced steps to deliver a successful four week datacentre migration.

When giffgaff’s datacentre supplier collapsed unexpectedly, Administrators restricted access to customer data (and backups), and said that the data centre could be turned off at any time, giving just 24 hours notice at one point. Pelicam were called-in to support giffgaff and were able to ensure successful data retrieval and migration within four weeks.

The Problem

With no physical access to servers, backups, data, and limited management of the database systems, giffgaff needed to urgently migrate 25 servers which would normally take six months. Pelicam recognised the need to balance speed with safety, whilst maintaining business continuity and reducing the impact on customers. 

The Solution

Giffgaff operates an Agile business model so Pelicam used small, iterative cycles to fit in with their methods. Traditional project planning would have been too prescriptive for giffgaff, so principles of the Pelicam Project Assurance Method (PPAM) were used to quickly prioritise tasks, and ensure that governance allowed swift decisions to be made when needed.

Critically, the Pelicam team dynamically balanced the risks – managing the concerns around the loss of customer data (and associated contingencies) with the need for an assured data migration and enterprise level rigorous testing.

The Results

Although it took three dry runs before pushing the button to switch to the migrated data, Pelicam proved that “practice makes perfect” by challenging traditional ways of working at every stage, and “innovating as we went” (Ross Catley, Senior Pelicam Practitioner).

Pelicam managed the project in such a way that the successful migration was undertaken within four weeks and customer inconvenience was minimised. Giffgaff’s new product development was quickly back on track, whilst the senior team put plans in place with new suppliers to reduce risks for the future.
