01 / Context

Start before the first export.

DOORS Next adds components, configurations, artifact types, and OSLC-linked context to the migration problem. The critical decision is not simply how to move artifacts, but how to translate configuration boundaries and reusable content into the target operating model.

Configuration-aware scope

Reliable artifact and link mapping

Preserved document structure

Repeatable delta migration

02 / Scope

What can move?

Migration scope should be decided by business value and evidence obligations—not by what is easiest to export. The following entities are typical starting points for DOORS Next.

Project areas

Components

Modules

Artifact types

Attributes

Links

Configurations

Attachments

03 / Mapping

Source concept → target intent.

The target should express how teams will work in Codebeamer. These are common design patterns, not guaranteed one-to-one conversions. The final decisions belong in a version-controlled mapping specification and must be validated against the source version, available APIs, and agreed target configuration.

Common DOORS Next source concepts and possible Codebeamer target patterns
DOORS Next	Possible Codebeamer pattern	Design note
Project area	Project / program structure	Split or consolidate based on ownership.
Component	Working-Set, branch, or governed project structure	Choose the boundary before detailed mapping.
Module	Tracker + document view	Preserve headings and ordered artifacts.
Artifact	Typed tracker item	Map artifact type to tracker or item type.
OSLC link	Association / external link	Decide whether the linked endpoint also moves.

04 / Failure modes

What can break.

Configuration ambiguity

Global and local configurations can expose different versions of the same artifact.

Reusable artifacts

One artifact appearing in multiple modules needs an intentional reuse pattern in Codebeamer.

OSLC boundaries

Links to systems outside the migration scope require a coexistence or relinking plan.

05 / Plan

Five steps to cutover.

Map configuration context

Document components, streams, baselines, and the versions visible in each migration wave.

Define structural rules

Decide how components, modules, types, and shared artifacts translate into Codebeamer.

Extract through supported APIs

Capture stable IDs, artifact content, types, attributes, module membership, and links.

Load in dependency order

Create structure and items first, then hierarchy, links, attachments, and evidence snapshots.

Reconcile by configuration

Validate not only totals, but the expected artifact versions in every agreed scope.

06 / Validation

Validate meaning, not only counts.

A defensible validation pack combines automated reconciliation with human review. It should show what moved, what changed by design, what failed, who accepted each exception, and which source snapshot the target represents.

Structural

Counts, types, hierarchy, fields, attachments.

Relational

Links, direction, coverage, reuse, versions.

Operational

Workflows, permissions, reports, user acceptance.

When scripts stop scaling

Build a repeatable workflow.

When repeated rehearsals, large volumes, relationships, or evidence requirements make one-off scripts difficult to control, purpose-built tooling can help. Product scope still needs to be confirmed against the source system, version, data model, and target design.

07 / FAQ

Early migration questions.

Can modules be migrated as documents?

They often can. A common target is a tracker presented through Codebeamer's document view, with headings and item order reconstructed and then validated.

What happens to global configurations?

They require a design decision. Map configuration intent to Codebeamer Working-Sets, branches, baselines, or governed project structures rather than assuming a one-to-one technical equivalent.

Can migration be incremental?

It can be when persistent source-to-target IDs and deterministic update rules are established from the first run.
