Data migrations are rarely seen as “value-added” technology activities, but rather as a “necessary evil” deriving from the need to consolidate storage, implement stronger technology controls, upgrade / replace systems, and merge / rationalize technologies. This makes keeping management focus – the holders of IT budget – a particular challenge. Therefore it is necessary to present a strong business case to them that outlines the business advantages of controlled data migrations, justified in traditional cost-benefit form. A clear migration must support that business case, bringing together all of the pieces of the puzzle – storage and tool vendor support, internal or external staffing, requirements, and performance metrics.
Where the enterprise already possesses staffing, tools, and experience, migrations become a matter of staffing costs and the objective becomes minimizing staff time necessary to perform migrations (accomplished through clear strategy, requirements, design, and implementation planning). Data migration tools can cost from tens to hundreds of thousands of dollars, and good data analysts and developers can cost from $80,000 to over $100,000 in major IT markets.
