Build a Znode 9 upgrade inventory before touching packages

Turn existing Znode 9 customizations into an upgrade inventory of business behavior, dependencies, permissions, target contracts, and acceptance cases.

An upgrade inventory traces each business behavior through its dependencies before selecting the next target vertical slice.

Inventory behavior rather than assemblies

An upgrade inventory should answer what a customization does for the business, not only which project contains it. A package list cannot reveal that an account-switching change affects prices, carts, authorization, and support workflows. Begin with user-visible behaviors such as quote editing, ERP delivery, custom attributes, payment initiation, search filters, and Page Builder content.

For each behavior, identify entry points, extension seam, data touched, external dependencies, authorization boundary, user roles, test evidence, operational owner, and acceptance criteria. Classify the result as native configuration, supported extension, project-owned customization, direct database dependency, obsolete behavior, or unknown. Unknown is a valid outcome that deserves investigation.

  • Behavior and affected readers.
  • Current source and target version.
  • Owner and redistribution status.
  • Data and integration dependencies.
  • Acceptance and rollback evidence.

Map risk and coupling

Record why a customization needs attention. A direct database query depends on schema shape; a service override depends on registration and method contracts; a payment change depends on the provider lifecycle. Name the specific uncertainty and the evidence needed to resolve it rather than assigning only a color or score.

The example is an assessment record for quote-line editing. Its field names belong to your project inventory, not Znode configuration. Add the exact source and target releases to the assessment alongside this behavior record.

    {
      "boundary": "service-registration",

    },
    {
      "boundary": "quote-dto",
      "action": "map-explicitly-to-application-model"
    },
    {
      "boundary": "calculation-result",
      "action": "reject-result-for-an-older-quote-revision"
    }
  ],
  "acceptanceCases": [
    "authorized-edit-recalculates-tax-freight-and-total",
    "unauthorized-account-edit-rejected",
    "older-calculation-cannot-replace-newer-result",
    "calculation-failure-blocks-confirmation"
  ],
  "releaseGate": [
    "exact-source-version-recorded",
    "exact-target-version-recorded",
    "target-seams-reviewed",
    "acceptance-cases-pass"
  ]
}

The three coupling entries become concrete review tasks: compare service registration, map the target quote response into your own quote model, and reject calculations for an older quote revision. The acceptance cases then prove authorized edits recalculate totals, unauthorized edits fail, and a failed calculation cannot be confirmed.

Choose vertical slices

Choose one complete behavior, such as changing a quote line and displaying its recalculated total. Trace it through UI, API, data, and external services, then adapt that path to the target release. This is a vertical slice: a small feature carried through every layer it needs.

For a Znode 9 patch upgrade, compare the source and target Framework 4.8 contracts. A Znode 10 migration additionally moves API customizations to ASP.NET Core and storefront behavior to Next.js. Keep the business acceptance cases stable while documenting intentional changes to models, permissions, storage, and calculation behavior.

  • Choose a bounded, high-value behavior.
  • Pin source and target baselines.
  • Document contract changes intentionally.
  • Prove success, failure, authorization, and recovery.

Create a living assessment

The inventory becomes the upgrade backlog and acceptance ledger. Update it when a dependency is removed, a release note changes an assumption, or a newly discovered integration expands scope. Connect each entry to its implementation and regression cases so the scope follows real behavior.

Before touching packages, obtain actual target release notes, compatible dependency information, and a permitted test environment. Schedule a decision point for behaviors that cannot be validated because of vendor, payment, or external system constraints.

Verification checklist

A complete first inventory has no unclassified customization, even if some entries are marked unknown. Each high-risk behavior has a named owner, target evidence needed, and a decision date. Reconcile the inventory against actual configuration and deployment assets before declaring scope stable.
