Job Summary

Dice, a leading career platform for tech professionals, is seeking a UNIX/Linux Migration Consultant for their client, NYC Department of Social Services. This is a 12-month contract role focused on migrating Solaris and AIX workloads to modern platforms like AIX 7.3, RHEL 9, and containerized environments (OpenShift 4.12+).

Key Responsibilities

  • Migrate Solaris 10 and 11 Global and Non-Global Zones to AIX 7.2/7.3 LPARs, RHEL 7/8/9 systems, and containerized environments.
  • Handle the hosting of operating system environments, including filesystems, applications, configurations, cron jobs, user accounts, and system integrations.
  • Address the technical complexity of transitioning from SPARC hardware and Solaris services to IBM Power10-based AIX platforms or container-native platforms.
  • Translate OS-level constructs and ensure seamless continuation of legacy workloads while adhering to modern security and performance standards.
  • Perform migration of the critical POS application from Solaris 11 to AIX 7.3, involving a complex transition from Veritas SFRAC to an Oracle ASM-based 8-node AIX 7.3 cluster. This includes managing Veritas clustering, Oracle database storage, kernel tuning, and Oracle RAC connectivity.
  • Identify, catalog, and evaluate legacy Solaris systems, applications, services, and configurations.
  • Develop migration strategies and prepare target environments (AIX LPARs, RHEL VMs, OpenShift containers).
  • Develop and execute cutover strategies for various system components.
  • Conduct post-migration validation, service checks, log audits, and user verification.
  • Migrate Solaris Logical Domains (LDOMs) to AIX 7.3 LPARs and RHEL 8/9 systems.
  • Host Solaris-based applications (Oracle tools, Apache, in-house binaries) onto AIX or RHEL 9.
  • Transition AIX Logical Partitions (LPARs) to AIX 7.3 LPARs.
  • Migrate standalone AIX 6.1/7.1 systems to AIX 7.3 on IBM Power10.
  • Transform Solaris-based services into OCI-compliant containers for OpenShift deployment.
  • Host existing containerized workloads into OpenShift 4.12+ environments.
  • Move essential system services (cron jobs, SFTP/FTP, logging agents) to RHEL 9 or OpenShift containers.
  • Migrate middleware applications from legacy Solaris and AIX systems to modern platforms.
  • Convert Solaris ZFS/UFS file systems into JFS2 (for AIX) or XFS/LVM (for RHEL).
  • Transfer user environments and authentication mechanisms.
  • Port and validate all custom shell and automation scripts.
  • Convert Solaris SMF and init.d services to RHEL systemd unit files or equivalent AIX startup services.
  • Deploy backup software clients, transitioning from NetBackup to Commvault where applicable.
  • Migrate system logging configurations to modern standards.
  • Validate that all applications and services operate identically post-migration.
  • Reconnect shared file systems and mounts (NFS, CIFS).
  • Migrate the POS application stack and its standby environment, including Oracle ASM and Oracle Data Guard configurations.
  • Conduct comprehensive validation and operational certification of the POS environment.

Required Skills and Experience

  • Proven experience in migrating Solaris and AIX systems to modern platforms (AIX 7.3, RHEL 9, OpenShift).
  • Expertise in migrating Solaris Zones (Global and Non-Global) and LDOMs.
  • Strong understanding of SPARC hardware and IBM Power10 systems.
  • Proficiency in containerization technologies (OCI, OpenShift 4.12+).
  • Experience with Oracle ASM, Oracle RAC, and Oracle Data Guard.
  • Familiarity with Veritas SFRAC, CFS, GAB/LLT clustering.
  • Skilled in converting SMF, init.d, and systemd services.
  • Experience with file system conversions (ZFS/UFS to JFS2/XFS/LVM).
  • Knowledge of user environment and authentication migration (SSH, sudo, PAM).
  • Scripting proficiency (ksh, bash, Perl).
  • Experience with backup software migration (NetBackup to Commvault).
  • Familiarity with modern logging standards (journald, rsyslog).
  • Excellent communication and problem-solving skills.
  • Ability to work independently and lead migration efforts.
  • Must provide two references with contact details.
