Mainframe and midrange migration

Reduce costs by bringing your midrange and mainframe applications to an agile cloud platform.

Ensure success with a reliable and scalable mainframe to cloud migration strategy

Modernise the mainframe and midrange applications you rely on by running them on Azure. Rapidly address your company's needs at scale using midrange and mainframe to cloud migration tools and services without sacrificing functionality, security or compliance.

Reduce costs and free up your budget to support digital transformation by migrating midrange and mainframe applications from expensive legacy systems to Azure. Save on hardware, software and management of these platforms. Save even more by implementing business continuity, disaster recovery or scalable solutions. With Azure, you pay only for consumption, not for the systems required to support these requirements.

As legacy programmers retire, it is becoming difficult to find talent who know how to use legacy development tools to maintain legacy applications. By moving midrange and mainframe applications to the cloud and using modern development tools such as Eclipse and Microsoft Visual Studio, you will expand the talent pool with new developers who can collaborate with legacy developers to continue evolving legacy applications.

Accelerate updating and deploying legacy applications by moving from a legacy waterfall development process to a modern DevOps environment. Instead of waiting six months or more to deploy a major update, deploy incremental, daily updates to support business requirements.

Legacy applications are limited to running on legacy platforms in the datacentre. Use migration tools and services to move these legacy applications to an x86 platform and take advantage of the cloud for running your mission-critical workloads.
