The 55-Question Assessment That Prevents Azure Migration Failures

The Meeting That Should Scare You

CIO: "We're migrating to Azure. How much will it cost?"

Consultant: "$800K, 18 months."

Reality: $2.3M, 28 months, half the apps still on-prem.

Why Migrations Fail

Not technical problems. Organizational problems:

  • Nobody knows what applications exist
  • Teams can't find installation media
  • License compliance is "figure it out later"
  • Dependencies discovered in month 14

The 55 Questions

Before touching Azure Migrate, answer these for EVERY application:

Application Basics

  1. What does this app do? (If nobody knows, retire it)
  2. Who owns it? (Name + phone number)
  3. Where's the installation media?
  4. What's the license model?

Dependencies

  1. What databases does it connect to?
  2. What APIs does it call?
  3. What calls it?
  4. What shared services does it use?

Current State

  1. How many VMs?
  2. What OS versions?
  3. What's the network topology?
  4. What's using public IPs?

Business Context

  1. What's the business impact if it's down?
  2. When can we migrate it? (Maintenance windows)
  3. Who approves changes?

The Problem

Teams skip this. They:

  1. Deploy Azure landing zones
  2. Start Azure Migrate
  3. Discover in month 6 nobody knows what they own

Then:

  • Budget doubles
  • Timeline extends
  • Political pressure builds
  • Consultants suggest "hybrid strategy" (translation: we failed)

What Actually Works

Phase 1: Discovery (Before Azure)

  • Application inventory
  • Dependency mapping
  • License audit
  • Owner identification

Timeline: 2-3 months

Cost: $50K-$150K

Value: Prevents $2M+ overruns

Phase 2: Rationalization

  • Retire 20-30% of apps (nobody uses them)
  • Rehost 40-50% (lift-and-shift)
  • Refactor 20-30% (modernize)
  • Retain 10% on-prem (compliance, cost)

Phase 3: Azure Deployment

Now you can actually use Azure Migrate successfully.
