After moving from IBM to Kyndryl, I kept as the main Support for IBM's internal z/OS systems. But with the systems migrations I had the opportunity to work on the process of Lift & Shift and Redeploying of some systems, which granted me a deeper understanding of how a z/OS system works. I also took part of some projects, for example, the implementation of MFA on Storage DASD boxes, increasing its security and reliability and upgrading the z/OS system from 2.2 to 2.4 version.Some of the… Show more After moving from IBM to Kyndryl, I kept as the main Support for IBM's internal z/OS systems.
