Fast, Non-Disruptive DS Disk Migrations — Planned or Emergency
Moving data between DASD subsystems is one of the most operationally sensitive tasks in a mainframe environment. Supportmyz specializes in DS disk migrations and quick swaps — whether you are upgrading to a newer DS platform, replacing aging hardware, consolidating storage, or responding to an unplanned hardware failure. We have executed DASD migrations of every scale and complexity, and we know how to move your data fast, cleanly, and without disrupting your production workloads.
Migration Methodology
We inventory your current DASD environment — volumes, capacity, utilization, and workload profiles — and identify all dependencies and constraints that will shape the migration plan.
We develop a detailed migration plan covering volume sequencing, copy methodology, cutover windows, rollback procedures, and integrity verification checkpoints — reviewed and approved before any data moves.
We execute the migration using non-disruptive copy techniques, monitoring progress in real time and managing the cutover from source to target with precision — keeping your production workloads running throughout.
Post-migration, we confirm full data integrity across all migrated volumes, validate application and system access, and provide complete documentation of the migration before declaring the project closed.
