MIGRATION OF PEOPLESOFT FROM ON PREMISE TO AWS Outcome

Customer Profile

Harvard University – One of the most elite education institutions in the world.

At A Glance

The key goal of this project was to migrate Harvard’s PeopleSoft implementation from on-premise to AWS. PeopleSoft is used for all Payroll, Benefits, and Pensions management. Harvard had tried many times over the past years to migrate and modernize their PeopleSoft implementation; however, all attempts did not fully achieve their goals. They were ten months into a two year plan to upgrade their PeopleSoft version and migrate from SunGard to VM Linux.

Lessons Learned

  • More thought exercises at the beginning would have eliminated rework and persuaded the customer should have chosen to go to AWS rather than VM initially.
  • Be cognizant and have a plan to address customer education and culture to ensure a successful transition. Some team members had a really hard time with the concept of “ephemeral” infrastructure and shutting legacy environments.
  • PeopleSoft can run very successfully in AWS and it is much cheaper than an on-premise implementation. In this case, it was more cost effective and customized than using Oracle’s PeopleSoft Cloud offering
