Cloud-Migration Planning That Starts With the Application Landscape

Before deciding what moves, what changes, and in what order, you need to know what you have, what each application does for the business, and what depends on what.

Useful EA supports cloud-migration planning: the application, dependency, and business-impact analysis that comes before the migration itself.

The Problem

Migration Plans Fail on What Nobody Wrote Down

A migration plan is only as good as the inventory beneath it. The surprises that derail migrations are rarely technical puzzles. They are an undocumented downstream feed, an application that turns out to support a critical business capability, an owner who was never consulted, or a system that should have been retired rather than moved.

Sequencing decisions are often made for infrastructure convenience: by data center, by server, by team. The business sees the result as a series of outages and broken interfaces, because applications that exchange data were moved months apart.

The planning work is to build a shared, trusted picture of the landscape first, then decide each application’s path and the order of the moves.

The Method

Understand, Decide, Sequence, Schedule

Cloud-migration planning is application portfolio work with a deadline. The steps below apply whatever migration approach and cloud provider you choose.

  1. Build an inventory people trust

    List every application in scope with its owner, contacts, vendor, and lifecycle state. Ask the people who run each department to confirm what is theirs.

  2. Relate each application to the capabilities it supports

    Business impact comes from capabilities, not servers. Knowing which capabilities an application supports tells you who will notice if a move goes wrong.

  3. Record application dependencies

    Capture the upstream and downstream application-to-application data flows as the people who run the applications understand them. Applications that exchange data must move together or have their interfaces planned.

  4. Decide each application’s path

    Some applications should be retired or replaced instead of moved. Record the disposition, and record migration-specific decisions such as the chosen approach in fields of your own.

  5. Group and sequence the moves

    Form migration groups from the dependency picture, and order them to minimize disruption to the most important capabilities.

  6. Turn decisions into dated work

    For each application, schedule the checklist of work a change requires, working back from the target date, and identify the stakeholders who must be notified.

Decisions It Supports

The Questions the Plan Should Answer

  • Which applications should move, change, or be retired before the migration
  • Which applications exchange data and must move together or have interfaces planned
  • Which business capabilities are affected by each migration group
  • In what sequence the groups should move to limit disruption
  • Who owns each application and must be consulted or notified
  • When the work for each application must start to meet a target date
How Useful EA Helps

Application Portfolio Manager Does Most of the Work

Application Portfolio Manager holds the inventory, dependencies, and change work. Architecture Repository adds structured technology and hosting relationships where you need them, and Capability Modeler provides the capability map applications link to.

Inventory, dependencies, and change work

Application Portfolio Manager

  • Bring in applications by CSV, from an AI assistant’s summary via JSON, or by reading them from ServiceNow or Vertice; re-imports update matching applications instead of duplicating them.
  • Record department owners and business, technical, and other contacts for each application.
  • Link each application to every capability it supports in your Capability Modeler map, and filter the portfolio by capability group.
  • Record upstream and downstream data flows and view them as a single-application diagram or a full network.
  • Add custom fields (text, number, or yes/no), such as a migration group or migration approach, and show them in the list and the printed report.
  • Set a disposition and schedule its checklist as a workback plan from a target date; items land on a shared, assignable worklist.

Technology and hosting relationships

Architecture Repository

  • Record applications, hosts, technologies, and their relationships using a metamodel you choose or define.
  • Only relationships the metamodel permits can be created, such as an application deployed on a host.
  • Validation findings show gaps; viewpoints focus on one question, such as what runs where.
  • Export the repository as JSON, or elements and relationships as CSV.

The capability map

Capability Modeler

  • Build or import the business capability map that applications are linked to.
  • Score capability maturity and see which capabilities strategy depends on most, so migration groups can protect them.

The Useful EA tools are separate applications that share one sign-in and one subscription. They do not exchange data automatically, with one exception: Application Portfolio Manager can link each application to capabilities in a model you build in Capability Modeler. Every tool exports its data, so you can carry findings from one into another yourself.

Product Boundary

What Useful EA Does Not Do

Useful EA is not a cloud-migration platform. It supports the planning, not the migration. It does not provide:

  • Automated cloud or infrastructure discovery
  • Runtime dependency discovery
  • Workload migration
  • Migration orchestration
  • Landing-zone implementation
  • Infrastructure provisioning
  • Cloud-cost optimization
  • Cloud-security assessment

Application dependencies in Useful EA are the data flows people record, import, or confirm, not connections discovered from running systems. Use Useful EA alongside your cloud provider’s migration and discovery tools.
