The company, which manages around $66.6 billion of funds under administration for over six million member accounts, said it will replace its legacy system with SAP ERP and use CSC to handle systems integration.
It is expected Superpartners will move to the new system by July 2009.
Superpartners CEO Greg Camm said the reason for the upgrade was simply that it had "outgrown its current systems".
"Superpartners has doubled in size over the past five years, and we now service over six million member accounts and 700,000 employers," Camm said.
"Migrating onto a new ERP system is absolutely essential for us to mitigate the costs of ongoing growth, and provide the sophisticated reporting and analysis required by our client Industry Funds."
The overall investment programme is funded through a recapitalisation of the company which has initially been underwritten by Superpartners' largest investors, including AustralianSuper, Cbus, HESTA, HostPlus and MTAA Superannuation Funds.
The company expects to make a further announcement soon in relation to its recent IT Infrastructure Managed Services tender, it said.
Last month, Superpartners said it expected to automate up to 25 percent of support calls by rolling out a self-service portal to its fund clients this month.
