Key Responsibilities:

1. 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.

1. 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).

1. 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.

1. 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).

1. 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.

1. 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.

1. 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.

1. Training and Knowledge Transfer:

• Documentation for Internal Teams: Create detailed user manuals and internal documentation on managing updated systems.
• Knowledge Sharing: Share insights and lessons learned from the migration process to help other teams with similar future upgrades or transitions.

1. Backup & Disaster Recovery:

• Backup Solutions: Ensure that backup solutions are in place for both Windows and RHEL systems
• Disaster Recovery Planning: Update disaster recovery plans for systems post-migration and test recovery procedures to ensure business continuity.

1. Post-Implementation Review:

• System Audits: Conduct post-migration audits to verify that all systems are fully functional, secure, and compliant.
• Post-Migration Optimization: Identify any post-migration system performance improvements, optimizations, or further enhancements needed.
