Most new IT systems in the 1980s and 1990s were implemented on minicomputers. These midrange computers replaced the older generation of mainframes, in the same way that minicomputers were replaced my personal computers and servers running Windows and Unix.

Twenty years on, there are still millions of these legacy systems, including over 500,000 OpenVMS systems. Many of these systems are still running business-critical applications. But it is becoming increasingly difficult to keep these legacy IT systems running as the availability of replacement hardware and skilled personnel reduces.

IT Challenges

Most modern IT departments are finding it difficult to support, enhance, or migrate these business-critical applications

  • Running old application software, written in legacy programming languages
  • Running on old operating systems, storing data in proprietary data formats
  • Without the modern tools and interfaces they are used to working with

In many cases, these challenges are compounded by

  • Original team members no longer available, and shortage of skilled replacements
  • Vendors going out of business or withdrawing support
  • Lack of documentation, database drivers, and tools to access data
  • Shortage of hardware replacements and peripherals

Whether IT departments need systems management, data integration, or migration and modernization they require expertise in proprietary data sources and legacy systems.

Data Sources

The majority of data held in legacy systems can be classified as

  • Applications
  • Hierarchical Databases
  • Indexed Flat Files
  • NoSQL Databases
  • Relational Databases
  • Spreadsheets
