  • Application Porting – Recompile C/C++/COBOL code for Linux (GCC/Clang); port ksh scripts to Bash; adapt HP-UX-specific APIs and libraries.
  • Database Migration – Transition Oracle, Informix, or Sybase databases to PostgreSQL, MariaDB, or EDB Postgres on Linux; schema/data migration, stored procedure porting.
  • Filesystem & Storage – Migrate VxFS to XFS/ext4/btrfs; LVM to Linux LVM; preserve data integrity with rsync or ZFS (if using ZFS on Linux).
  • Security & Compliance – Map HP-UX RBAC/privileges to Linux SELinux/AppArmor/PAM; encryption, auditing, and compliance (PCI-DSS, HIPAA).
  • High Availability – Replace MC/ServiceGuard with Pacemaker/Corosync, DRBD, or cloud-native HA; replicate failover configurations.
  • Batch & Scheduling – Migrate cron/at jobs and custom schedulers to Linux cron, systemd timers, or Ansible Tower.
  • Testing & Cutover – Parallel testing, performance benchmarking, phased rollout, and minimal-downtime cutover with rollback.
  • Post-Migration Support – Ongoing Linux administration, monitoring, tuning, and team training.
