Migrate legacy LAPS with bounded side-by-side coexistence

Treat this document as a focused evidence review: Migrate legacy LAPS with bounded side-by-side coexistence. Only the official source and traced locations below supply facts. Confirm applicability before acting.

Source fact:

The official Prepare for Windows Local Administrator Password Solution (LAPS) Deployment and Migration from Microsoft supports the following bounded statements:

• Microsoft documents migration from legacy Microsoft LAPS to Windows LAPS. The research record locates this support at Opening overview.
• Side-by-side coexistence is possible only when the two policies target different local accounts, and migration away from legacy LAPS remains the goal. The research record locates this support at Opening overview.

Do not import neighboring assumptions into the source record. The supported task is a scoped comparison involving managed accounts, policy assignment, password storage, directory permissions, retrieval roles, rotation, and recovery scenarios and the conditions the source actually describes.

What the source does not establish

Monitor successful transition before removing legacy software or policy. A correct source interpretation can still be inapplicable to a particular design. Confirm Active Directory or Entra ID, Windows DNS, policy processing, device identity, time, and protected administrative workstations, ownership, and change authority instead of treating documented behavior as a deployment guarantee.

Applicability questions

• For source statement 1 at Opening overview, which observable configuration, record, or test can confirm applicability here?
• For source statement 2 at Opening overview, which observable configuration, record, or test can confirm applicability here?
• What inventory proves which parts of managed accounts, policy assignment, password storage, directory permissions, retrieval roles, rotation, and recovery scenarios are in and out of scope?
• Which condition in Active Directory or Entra ID, Windows DNS, policy processing, device identity, time, and protected administrative workstations must be healthy before evidence is trustworthy?
• What result would disprove the working assumption and return the issue to the owner?

DSE recommendation:

DSE recommends using the cited source as the evidence anchor for this decision. Use a two-person review for the source interpretation and the resulting operational decision. Record the source location, examined part of managed accounts, policy assignment, password storage, directory permissions, retrieval roles, rotation, and recovery scenarios, observed and expected states, owner, and reason for deviation.

For an approved change, define prerequisites, a limited test path, success and stop conditions, monitoring, and rollback. Check Active Directory or Entra ID, Windows DNS, policy processing, device identity, time, and protected administrative workstations in design order. Protect credentials, keys, recovery material, personal data, and sensitive topology in evidence.

Verification and evidence

Evidence should let another reviewer reproduce this decision. Retain observations beside the traced locations Opening overview; Opening overview. Favor policy exports, directory access-control entries, sanitized client events, rotation tests, retrieval authorization, and exception records, linked to stable identifiers, time, and operator.

Keep before-state evidence, approval, test or change result, exceptions, and after-state evidence together. Use an approved lab, window, or nonproduction path for risky tests. Set a recheck trigger for version, architecture, dependency, vendor, incident, or ownership change. A check proves only what was observed.
