A lot of IMS systems were set up a long time ago, and have been kept that way for years under the mantra "if it ain't broken, don't mess with it". But what about when you do have to modernise things? This presentation will showcase a project of implementing IMS HP Tools, adopting IMS Catalog and IMS Connect, along with IMS managed ACBs, all in under a year, and future areas of consideration. Along with the lessons learned, a few useful tricks for populating IMS Catalog from old copybooks will be demonstrated.
