Legacy System Modernisation Planner

This planner is designed to help you evaluate your existing systems and prioritise modernisation efforts. Use it as a guide during internal discussions or with your IT consultant.

Step 1: Identify Legacy Systems

• List all core business systems and their purpose
• Note the year of implementation and last upgrade
• Indicate vendor support status (active, limited, discontinued)

Step 2: Assess Pain Points

• Performance bottlenecks
• Security vulnerabilities
• Integration challenges
• High operational costs

Step 3: Determine Modernisation Options

• Can the system be rehosted to the cloud?
• Is partial replatforming feasible?
• Does the business justify full refactoring or replacement?

Step 4: Prioritise by Impact

• Rank each system based on:
• Business criticality
• Ease of transition
• Cost/ROI
• Urgency due to remote access or pandemic-driven needs

Step 5: Plan & Consult

Define a phased roadmap and consult an IT expert for a detailed transition strategy. Start with low-risk, high-impact changes.
