AIX to Linux Migration
Expert migration services from IBM AIX on Power Systems to Linux — porting applications, ksh scripts, databases (DB2/Oracle), and workloads to cost-effective Linux platforms (AlmaLinux, Rocky, RHEL, Ubuntu LTS, SLES) with minimal disruption and maximum performance.

IBM AIX on Power Systems remains prevalent in banking, insurance, retail, and manufacturing — but escalating licensing costs, limited innovation, and talent scarcity make Linux the superior long-term choice. Zwiegnet delivers low-risk, phased migrations that preserve business logic while unlocking scalability, open-source tools, and cloud readiness.
Our AIX to Linux migration services include:
- Assessment & Planning – Full inventory of AIX applications (C/C++, COBOL, ksh), LVM filesystems, JFS2 storage, dependencies, and compliance requirements; cost analysis and target Linux distribution selection.
- Application Porting – Recompile or refactor C/C++, COBOL, and other AIX-specific code for Linux (GCC/Clang); adapt XL C/C++ to GNU/LLVM, and port ksh scripts to Bash or POSIX-compliant shells.
- Database Migration – Transition IBM DB2 on AIX to PostgreSQL, MariaDB, or EDB Postgres on Linux; schema conversion, data migration, stored procedure porting, and performance tuning.
- Oracle on AIX to Linux – Move Oracle Database from AIX to Oracle on Linux or open-source alternatives; GoldenGate replication, schema migration, and optimization for x86/ARM architectures.
- Filesystem & Storage – Migrate JFS2 to XFS/ext4/btrfs; LVM to Linux LVM; preserve data integrity with rsync, tar, or ZFS if using ZFS on Linux.
- High Availability & Clustering – Replace HACMP/PowerHA with Pacemaker/Corosync, DRBD, or cloud-native clustering; replicate HA configurations with minimal downtime.
- Security & Compliance – Map AIX RBAC/privileges to Linux SELinux/AppArmor/PAM; encryption, auditing, and compliance (PCI-DSS, HIPAA, SOX) on Linux.
- Batch & Scheduling – Migrate crontab jobs, at/batch, and custom schedulers to Linux cron, systemd timers, or Apache Airflow/Ansible Tower.
- Testing & Cutover – Parallel testing, performance benchmarking (AIX vs Linux), phased rollout, and minimal-downtime cutover with rollback plans.
- Post-Migration Support – Ongoing Linux administration, monitoring (Prometheus/Grafana), tuning, and team training.
Ideal for: banks, insurance companies, retail chains, utilities, and enterprises still running AIX on IBM Power Systems — seeking 50-80% cost reduction, modern DevOps, and cloud flexibility.
