RSA Insurance

Insurer executes an enormous data migration to effect digital and cloud strategies

RSA Insurance is one of the world’s oldest general insurers, providing insurance products and services to individuals and businesses of all sizes. The RSA mainframe and systems support major operations representing approximately 4.5 million policies.

Business challenge

RSA’s mainframe operating system and most of its systems software relied on legacy technology that was losing support. The challenge was to enable digital-first and cloud-first strategies and to mitigate material IT risk. To accomplish that, RSA needed to move its infrastructure, software, and mainframe data to a robust and security-rich cloud architecture.


The migration to cloud is a key component of RSA’s strategic IT infrastructure modernization goals. Kyndryl™ helped RSA modernize and transform with unique hybrid solutions including managed extended cloud IaaS for IBM Z®. The transformation allows RSA to adopt smart technologies to create and automate industry-leading actuarial models for its analysts.

RSA sees significant cost savings and greater cost predictability through the move from traditional architecture to cloud. Changing from a fixed to a variable cost model will enable flexibility and future growth.

Background and team goals

The RSA mainframe is one of RSA’s vital systems, sending over 4,000 files to other application environments each week. RSA’s first mainframe computer went live in 1969 with punch cards and flat files on an IBM 360/65 with 512k RAM.

The project team’s primary task was to migrate three mainframe environments to the IBM Z managed extended cloud infrastructure, or zCloud. The data consisted of 11 LPARs (logical partitions), 85 terabytes of physical disk data that sat across 10,000 logical volumes, and 85 terabytes of tape data that sat on 25,000 virtual tapes.

RSA was keenly aware of the critical advantages in moving to digital and cloud capabilities—and of the complexities of executing large legacy migration projects. Meeting the challenge would require deep technical expertise and a lot of tight planning, collaboration, and management. In 2020, during the COVID-19 pandemic, RSA chose IBM® Infrastructure Services, now known as Kyndryl, to help lead its IT transformation project.

Unique challenges

Given the ongoing pandemic, few key team members were ever able to meet in person. The project plan was complex and had no room for missed dates. Across 12 mainframe technical functions, thousands of test cases, and stakeholders from 6 partner and vendor organizations, RSA had to accomplish the migration with minimal impact to staff, customers, and the business—all in a compressed timeframe.

Prior to the migration, the project team removed or replaced hundreds of instances of redundant software and staged two dry run events. The first dry run was to prove the LPARs could be successfully migrated and that all the systems could be successfully deployed on zCloud. The second dry run added fine-tuning and application testing, such as for software interfaces. The team ultimately managed and coordinated across teams from multiple strategic partner organizations to deliver the project ahead of schedule, with no negative impact to RSA’s business operations.

Smooth transfer of knowledge was also critical to project success. More than 120 remote classroom-based virtual sessions, with playbacks and specific one-to-one sessions, were held so that the new team could capably take on post-migration responsibilities.

While there were many logistical problems solved over the intense 6-month assignment, the most unexpected was having to dig up the road on the A24—a major London route—with two weeks notice to replace a connection!

Developing a competitive edge through IT innovation

Through IT modernization, RSA aims to improve the costs, functionalities, and overall predictability of its service delivery. As financial and insurance markets transition to digital, the move to cloud also gives RSA the flexible architecture it needs to innovate new capabilities and prepare for future competitive trends.

Akhlas Hafiz, Head of Digital Transformation, Technology Change and Delivery, describes the opportunity this way:

“We’re looking at how we really get the most out of the IT investment longer term. We’re looking at digital from a customer UX perspective, monetizing cloud as an asset for our business, and industry trends such as artificial intelligence and machine learning—and what agility we need to have in our architecture to better develop those.”

Protecting data, applications, and environments

In addition to the LPAR migrations to zCloud and extensive software cleaning and updates, Kyndryl helped RSA implement high-capacity network connectivity. The network connection is designed to interoperate easily with multiple suppliers, geographies, and technologies between itself and the Kyndryl data centers.

The Kyndryl zCloud solution for RSA is built to help deliver economies of scale in a securely hosted, high-capacity, high-availability multitenant mainframe environment for the primary and backup data centers. The solution for RSA is also designed to be General Data Protection Regulation (GDPR) compliant, and support end-to-end encryption, including tape, storage and in-flight data across networks.

“The advantages of these data centers are the high availability and security-rich features. We’re able to operate an LPAR model created to offer highest levels of security. All of which are integral to the solution designed and delivered for RSA. And it also includes additional subsystem isolation geared to protect data, protect applications, and to protect the test and production environment.”
