Industry figures


Data migration facts

• 2012 – Estimated $8 billion worldwide in data migration services

• Average cost of large data migration projects $800,000

• Data migrations account for 60% of large enterprise projects

• 1999 – 2007 84% of data migrations went over budget and time

• 2007 – 2012 62% of data migrations completed on time

Challenges and risks


Challenges

• Maintaining consistent data availability

• Avoiding risks of compromising data during a migration

• Keeping costs down by avoiding scheduled outages and minimizing downtime

• Moving storage investment into production quickly without impacting existing operations

• Finding a solution that is storage vendor neutral


83% of DIY migrations have surprises!
