Trigyn's direct government client in Austin, Texas has a requirement for Support System Administrator. The particulars of the opportunity are below:
Description:
The Support System Administrator will be responsible for supporting the migration and modernization of EOL systems, including legacy systems running older versions of Windows and Red Hat Enterprise Linux. 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.
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 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.
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.
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.
Skills & Qualifications:
? Experience with RHEL 5/6/7/8/9, and Windows Server (2008-2022).
? Proficiency in system administration for both Linux (RHEL 5/6 and RHEL 7/8/9) and Windows environments.
? Advanced troubleshooting skills for legacy systems (RHEL 5/6 and older Windows versions).
? Experience with in-place upgrades and fresh installs for RHEL and older Windows versions to Windows Server.
? Familiarity with configuration management tools (e.g., Ansible for RHEL, PowerShell, SCCM, for Windows).
? Proficient in system automation and scripting (Bash, PowerShell, Ansible).
? Strong security knowledge, including patch management, system hardening, and vulnerability scanning for both Windows and RHEL systems.
? Experience with backup and recovery solutions for legacy systems.
? Experience with virtualization technologies (e.g., VMware).
Deliverables:
? Migration plans and timelines for legacy systems. Weekly upgrades should be scheduled with change control.
? Backup and disaster recovery strategies for RHEL and Windows systems.
? Post-migration system configurations and updates.
? Regular migration status reports and post-migration review reports.
