Looking to modernize your legacy core? You’ll need to migrate your data to the new platform.

Traditionally this was a risky process involving moving all your data across in one go—a so-called “big bang” migration. But now there’s another way.

One way to de-risk your transformation program is to run your new core alongside your legacy core as you migrate. We call this coexistence. Not only does this sidestep the huge risks associated with “big bang” migrations, but it also allows you to deploy, migrate, test and learn from small tranches of your portfolio in a controlled approach.
