Case Study: Adventist Health achieves minimal downtime and uninterrupted 24/7 clinical access with Vision Solutions' Upgrade/Migrate While Active

Adventist Health - Customer Case Study

Adventist Health, a multi-state healthcare network supporting hospitals, clinics and retirement centers around the clock, faced performance problems with an aging IBM AS/400 model 730. Migrating to a new IBM System i model 570 risked up to 20 hours of downtime—an unacceptable interruption for continuous patient-care operations.

Adventist Health deployed Vision Solutions' Upgrade/Migrate While Active (iTera HA) to run the new System i 570 in parallel with the production server, synchronizing 800 GB over several evenings with no user impact. The parallel migration drastically reduced downtime (cutting it to a fraction of the original estimate), completed the cutover in one-seventh of the expected time, avoided extra staffing shifts, and left the organization with ongoing high-availability protection.
