The role will focus on upgrading these systems to supported OS versions (e.g., Windows Server 2016/2019/2022, RHEL 5/6/7/8/9\) to ensure improved security, performance, and operational continuity. These positions may be as long as two years. CANDIDATE SKILLS AND QUALIFICATIONS Minimum Requirements: Candidates that do not meet or exceed the minimum stated requirements (skills/experience) will be displayed to customers but may not be chosen for this opportunity. Years Required/Preferred Experience 8 Required RHEL and Windows OS OTHER SPECIAL REQUIREMENTS Key Responsibilities: System Assessment \& Planning: Assess Legacy Systems: Conduct detailed assessments of existing EOL systems, including Windows Server (2012 and older) and Red Hat Enterprise Linux (RHEL 5, 6,7 and newer). Identify Priorities: Prioritize migration based on system criticality, security risks, and operational needs. Develop Migration Strategy: Create a comprehensive plan for transitioning legacy RHEL and Windows systems to supported versions, including risk assessments, upgrade paths, and timelines. System Migration: Legacy OS Migration: Migrate RHEL 5/6 and older Windows Server systems to newer, supported OS versions (RHEL 8/9, Windows Server 2022/2025\). Upgrade Path Planning: Perform in\-place upgrades as last resort. Primary job is to preform a reinstallation, following best practices to ensure compatibility and minimize downtime. Data Backup \& Recovery: Implement data backup and recovery strategies before, during, and after the migration, with a focus on reducing potential data loss during the upgrade process. Post\-Upgrade Validation: Validate the system's functionality after the upgrade (e.g., performance checks, compatibility testing of critical applications, system services, and networking configurations). Configuration Management: System Reconfiguration: Reconfigure system services and settings (e.g., networking, storage, security settings) after OS upgrade. Configuration Management Tools: Utilize tools like Ansible for RHEL configurations and PowerShell for Windows configurations to maintain consistency across systems. Automation Scripting: Write and maintain automation scripts for repetitive tasks across both Windows and Linux systems. Security Enhancements: System Hardening: Perform system hardening tasks on RHEL and Windows Server systems before and after migration to mitigate security risks. Patch Management: Apply security patches and updates for both RHEL and Windows servers. Ensure that legacy systems are brought up to current patch levels before the upgrade. Vulnerability Remediation: Run vulnerability scans and perform security updates to address any issues uncovered during the migration process. Compliance Assurance: Ensure all systems meet internal security policies, compliance regulations, and industry standards (e.g., CIS Benchmarks, NIST). Troubleshooting and Support: Issue Resolution: Act as the point of escalation for system issues encountered during the migration process, especially for legacy RHEL 5/6 and older Windows versions. Post\-Migration Support: Provide ongoing support for both Windows Server and RHEL systems after migration, addressing system issues, performance concerns, or compatibility problems. Problem Solving: Troubleshoot OS\-level issues and application problems on both Windows and RHEL systems post\-migration, ensuring high availability and reliability. Documentation and Reporting: Migration Documentation: Maintain detailed documentation of the migration process, including steps taken, configurations changed, and any issues encountered and resolved. System Configuration Records: Update system configuration records post\-migration to reflect the new OS and environment. This will be reflected in the CMDB as well as the TRP list. Progress Reporting: Provide regular updates and reports to stakeholders on migration status, challenges, and milestones achieved. Collaboration and Coordination: Cross\-Functional Collaboration: Work closely with other IT teams (e.g., networking, database admins, application owners) to ensure smooth integration of migrated systems. Vendor Coordination: Coordinate with third\-party vendors or support services as needed, especially for issues related to legacy systems or proprietary software running on older OS versions. End\-User Communication: Communicate with end\-users and stakeholders about any system downtime, changes, or disruptions during the migration process. Training and Knowledge Transfer: Documentation for Internal Teams: Create detailed user manuals and internal
