  • Demonstrable cost savings or performance improvements each quarter

Azure Monitor

Business Purpose: Comprehensive monitoring solution for infrastructure, applications, and network.

Capability Business Benefit Typical Results
Infrastructure Metrics Visibility into system health Early detection of potential issues
Application Insights End-user experience monitoring Improved customer satisfaction
Log Analytics Troubleshooting and trend analysis Faster resolution of problems
Alerting Proactive notification Reduced mean time to resolution

When to Use: Set up before migration cutover and maintain as a permanent part of your operations.

Success Metrics:

  • 95%+ of issues detected by monitoring before end-users report them
  • Average alert-to-resolution time under 2 hours for critical systems

⚠️ Troubleshooting Guide: Common Issues & Solutions

Despite careful planning, issues can arise during migration. Here’s how to address common challenges from a business perspective.

Pre-Migration Issues

Challenge Business Impact Solution Approach Preventive Measures
Incomplete Discovery Surprise applications or dependencies Conduct additional discovery sessions with business units Include business stakeholders in validation workshops
Unrealistic Timelines Missed deadlines, rushed execution Re-baseline project with realistic estimates Build 20-30% buffer into initial plans
Skill Gaps Delayed implementation, quality issues Engage partners or training resources Assess team capabilities early, train proactively
Unclear Success Criteria Inability to validate success Define specific, measurable objectives Create formal success criteria with stakeholders

Migration Execution Issues

Challenge Business Impact Solution Approach Preventive Measures
Performance Problems Poor user experience Rapid assessment and remediation team Test thoroughly before full cutover
Extended Downtime Business disruption Invoke rollback procedures if necessary Practice cutover procedures multiple times
Security or Compliance Gaps Regulatory risk Immediate remediation of critical issues Pre-migration compliance validation
Integration Failures Broken business processes Focused technical response team Map and test all system integrations

Post-Migration Issues

Challenge Business Impact Solution Approach Preventive Measures
Cost Overruns Budget exceptions Immediate optimization assessment Implement proper tagging and budgets upfront
User Resistance Reduced productivity Enhanced communication and training Involve users early in the process
Operational Confusion Support delays Clarify responsibilities and procedures Define operational model before migration
Performance Degradation Business slowdown Technical optimization assessment Establish performance baselines and monitor

Escalation Framework

When issues arise, follow this structured approach to resolution:

  1. Assess Impact:
    • How many users/systems are affected?
    • Is there a workaround available?
    • What is the business impact of the issue?
  2. Categorize Severity:
    • Critical: Business stoppage, no workaround, revenue impact
    • High: Major function impacted, limited workaround
    • Medium: Function impacted, workaround available
    • Low: Minor issue, minimal business impact
  3. Engage Resources:
    • Critical/High: Activate incident response team
    • Medium: Assign to migration team with timeline
    • Low: Document for planned resolution
  4. Communicate Status:
    • Share transparent updates with defined frequency
    • Focus on business impact and resolution timeline
    • Document lessons learned for future migrations

Pro Tip: “Create a dedicated ‘SWAT team’ of technical and business experts who can quickly address critical issues during migration cutover periods. This team should have decision-making authority to resolve problems rapidly.”
