System Upgrades

Absolutely. Buchanan Technologies specializes in seamless transitions from legacy systems to modern cloud infrastructures. Our comprehensive services include cloud migration, infrastructure support, and digital transformation strategies tailored to your business needs. We ensure minimal downtime and enhanced scalability, positioning your organization for future growth. ​  

Several widely used technologies are reaching their end-of-life (EOL) in 2025, meaning they will no longer receive security patches, updates, or vendor support. This introduces serious security and compliance risks for organizations still relying on these platforms. 

Key technologies going EOL in 2025: 

• Windows Server 2012 / 2012 R2 – End of Extended Support in October 2025 

• Microsoft SQL Server 2014 – End of Support in July 2024, with extended options ending soon after 

• Red Hat Enterprise Linux 7 (RHEL 7) – Support ends June 30, 2024 

• Oracle E-Business Suite 12.1 – No Premier Support after December 2021, but businesses are still transitioning from it 

• IBM AIX 7.1 and other UNIX-based systems used in legacy enterprise environments 

• Windows 10 (certain editions) – Begin phasing out in 2025 

• Third-party and custom legacy applications running on deprecated platforms 

Buchanan Technologies supports businesses by conducting thorough EOL assessments, creating upgrade roadmaps, and executing secure migrations to supported systems or cloud platforms. Our services cover everything from operating system upgrades to cloud transitions and application modernization, with a strong focus on minimizing downtime and aligning the upgrade with business continuity and compliance goals.

You can minimize downtime during system upgrades by following a structured and methodical approach. Buchanan Technologies can help by leveraging the following strategies: 

• 8-Phase Upgrade Methodology: Includes review, audit, backup, pre-upgrade planning, upgrade execution, post-upgrade analysis, system tuning, and ongoing support 

• Pre-upgrade Scheduling: All upgrade activities are planned outside peak business hours to minimize disruption 

• Stakeholder Coordination: We work closely with your internal teams to align on timing, testing, and contingency planning 

• Upgrade Simulations: Dry runs and simulations are conducted in staging environments to identify risks before live deployment 

• Rollback Planning: A robust rollback strategy ensures systems can be quickly restored in case of unexpected issues 

• Real-time Monitoring: Upgrades are tracked in real time to address any anomalies immediately 

• Post-upgrade Support: Dedicated engineers remain available post-deployment to ensure system stability and address any concerns 

This methodical approach ensures continuity, performance, and user productivity throughout the upgrade process, and Buchanan can guide you through every step. 

Buchanan Technologies provides comprehensive upgrade support for a wide range of systems and technologies, including: 

• Operating Systems: Windows, Linux, Unix, and legacy OS platforms 

• Servers and Storage: On-premises, hybrid, and cloud-integrated infrastructure 

• Network Infrastructure: Routers, switches, firewalls, and wireless systems 

• Databases: Microsoft SQL Server, Oracle, MySQL, and other enterprise databases

Whether you’re modernizing outdated systems or migrating to the cloud, Buchanan ensures every upgrade is secure, efficient, and aligned with your business goals. 

Security is embedded in every phase of Buchanan’s upgrade methodology. With cyber threats evolving rapidly, an upgrade without strong security controls can expose your business to serious risks. Buchanan goes beyond simple patching by integrating multi-layered security frameworks throughout the process. 

Buchanan’s security measures during upgrades include: 

• Pre-upgrade risk analysis and vulnerability scanning to identify existing threats 

• Role-based access controls (RBAC) to limit unauthorized access during upgrades 

• Secure data handling protocols and encryption during backups, transfers, and migrations 

• Next-generation firewall (NGFW) integration and intrusion prevention systems (IPS) 

• Zero Trust policies to prevent lateral movement during system changes 

• Post-upgrade compliance checks against NIST, HIPAA, GDPR, and other industry standards 

In addition, Buchanan conducts end-to-end audit trails and logs every activity, ensuring full traceability and transparency for compliance and internal IT governance.

While many IT service providers offer system upgrades, Buchanan Technologies distinguishes itself through delivering a unique combination of depth, flexibility, and outcome-driven strategy. 

Key differentiators: 

• Industry-specific expertise – Proven success upgrading systems in healthcare, retail, government, education, and manufacturing 

• Proprietary 8-phase upgrade methodology that ensures structure, precision, and minimal disruption 

• In-house certified professionals across Microsoft, Cisco, VMware, Oracle, IBM, and more 

• Hybrid and multi-cloud integration specialists 

• U.S. and Canada-based service centers with 24/7/365 availability 

Compared to other providers, Buchanan offers a more strategic and comprehensive approach. Instead of delivering one-size-fits-all solutions, we tailor each upgrade to align with your long-term IT roadmap and business priorities. Our cross-platform expertise and enterprise-grade methodology ensure upgrades are handled with precision and foresight, while our post-upgrade tuning and support services provide lasting value well beyond deployment.
