File Access Across Organizations From Day One. No Data Migration Required.

Transaction close and IT integration operate on different timelines. The transaction completes on a fixed date, while directory consolidation, tenant merges, and file server rationalization typically require 12 to 24 months.

MyWorkDrive addresses the interval. File shares from either organization are published over HTTPS, each user population authenticates against its own directory, and cross-entity access is scoped to specific folders, without a tenant merge, directory consolidation, or relocation of data.

File Access Constraints In Post-Merger IT Integration

01Separate directories, no trust relationship

Each organization operates its own AD forest and Entra tenant. A forest trust requires a security review, a network design, and a change window.

02Integration timelines exceed transaction timelines

Finance, legal, and operations require shared documents in the first week. Directory consolidation is a multi-quarter programme.

03Premature migration risk

File migrations executed in the opening months are frequently repeated once the integration plan is settled, and they compromise audit continuity.

04Divestiture and TSA separation requirements

Under a Transitional Service Agreement, the divested entity requires continued, scoped, time-bound access to defined data.

Cross-domain File Access Requirements During Integration

An access gateway is not an integration strategy. It does not merge directories, rationalize the storage estate, or determine target-state architecture. What it provides is separation of user access from infrastructure integration, so that the business obtains working file access at close while IT executes consolidation on a schedule set by the integration plan rather than by user pressure.

M&A File Access Scenarios: Day One, Diligence, Divestiture

DAY ONE

Cross-Entity Access Prior To Directory Work

Integration finance requires the target's shared drives at close; the target's leadership requires corporate policy libraries. Each population receives the specific shares it needs, with no directory consolidation required.

DUE DILIGENCE

Diligence Data Room On Controlled Infrastructure

Watermarking, download restriction, expiring access, and per-file audit records applied to material that is never uploaded to a third-party repository.

DIVESTITURE / TSA

Time-Bound Access For A Carve-Out

Access scoped to the folders named in the Transitional Service Agreement, every action logged, and access terminated at the end date with supporting evidence.

STORAGE CONSOLIDATION

Inherited File Servers, NAS, And Tenants

Each acquisition introduces additional servers, appliances, and tenants. All are presented through one interface while rationalization proceeds on its own schedule.

HOLDING COMPANY

Multiple Operating Companies, One Access Layer

Portfolio and holding company structures in which each entity retains its own identity and storage by design, and consolidation is not an objective.

Security And Compliance Controls For M&A File Access

The three questions raised in every integration security review: which directory governs authorization, whether access can be evidenced and revoked, and where data resides.

Identity stays with each entity

Each organization authenticates against its own Active Directory, Entra ID, or SAML provider. A gateway is deployed per entity, so no directory merge or tenant consolidation is required.

Scoped, revocable, evidenced access

Share and folder-level scoping, watermarking, download restriction, and defined expiry. Every action logged with SIEM export for integration audit or TSA close-out evidence.

Data residency preserved

Files remain on the originating servers, appliances, tenants, or cloud storage. No copy is created, which preserves residency commitments and regulatory holds through the transition.

Mergers and acquisitions file access FAQ

How can two merged companies share file access before directories are consolidated?

Each organization deploys a gateway against its own directory, and users reach entitled shares via browser, mapped drive, or mobile client. Neither directory is merged and no data is relocated. Active Directory deployments place the gateway in a resource domain with a trust: two-way trusts support SAML single sign-on, one-way trusts support username and password login.

Should file servers be migrated immediately after an acquisition?

Generally not. Target-state architecture is rarely settled in the opening months, so early migrations are frequently repeated and can compromise audit continuity. Establishing an access layer first allows users to work while the rationalization plan is finalized.

How does this apply to a divestiture or Transitional Service Agreement?

Access for the divested entity is scoped to defined shares and folders for the TSA duration, every access is logged, and access is revoked at the end date. Because no data was copied, separation is an access change rather than an extraction project.

Can an acquired company retain its own Entra ID tenant?

Yes. Each entity may retain its own tenant and identity provider, which suits holding company and private equity structures in which operating companies remain separate by design.

Does this replace Active Directory consolidation?

No. It removes the dependency between user access and directory consolidation, allowing consolidation to proceed on the integration plan's schedule rather than remaining on the critical path for day-one access.

Can it serve as a due diligence data room?

Yes, hosted on infrastructure the organization controls. Watermarking, download restriction, expiring links, and per-file audit records apply to material that never leaves that infrastructure.
