Strategic Migration Momentum from Day One

A secure, defensible, and leadership-led pathway from legacy eDiscovery to RelativityOne—engineered to preserve continuity, accelerate value, and enable day-one use of analytics and Relativity aiR™.

HaystackID® delivers end-to-end migrations from legacy Relativity Server and other review platforms to RelativityOne, led by senior program ownership and governed by a matter-based methodology with embedded validation. Certified in the RelativityOne Data Migration competency, HaystackID manages discovery, planning, movement, and verification of evidentiary data and configurations—issuing audit-ready documentation and post-cutover enablement so teams can immediately leverage analytics and Relativity aiR. This matters because legacy estates increase risk and cost, regulators expect defensible lineage, and consolidation unlocks cloud performance and AI-assisted review. Vendor-reported examples note up to four times faster processing and up to 80% reduction in review time when properly implemented (outcomes vary by data, configuration, and workflow). The offering converts an inevitable transition into a durable operational advantage, providing predictable timelines and budgets, minimizing disruption to active matters, accelerating time to value, and offering a clear path to decommission legacy infrastructure.

A dedicated senior director of client services aligns legal, business, and technical tracks from kickoff through post-cutover. In parallel, a data migration project consultant designs and governs chain-of-custody controls—hashing, counts, targeted sampling, and exception logging—so every movement is auditable, and integrity is preserved while live reviews continue.

"A migration is not just a data transfer—it’s an operational transition where continuity and defensibility are non-negotiable."

Key Features

The program blends accountable leadership, tailored execution, and auditable validation to ensure your data and configurations land in RelativityOne ready for immediate analytics and Relativity aiR engagement—all while maintaining the control and continuity required for judicial and regulatory scrutiny.

  • Executive Ownership
    Single accountable leader for planning, stakeholder alignment, risk governance, and cutover orchestration.
  • Embedded Validation
    Hashing, counts (items/sets), targeted sampling, and exception logs with tracked remediation at each stage.
  • Continuity by Design
    Calibrated cutover windows to reduce downtime, documented rollback options per wave.
  • Day-One Enablement
    Post-cutover health checks, user/role mapping, and targeted enablement for analytics and Relativity aiR.
  • Matter-Based Methodology
    Workflows tuned to each matter’s complexity, sensitivity, and activity level; representative pilots validate throughput and controls before scaling.
  • Context Preservation
    Structured data, custodial collections, review sets, configurations, and analytics artifacts are maintained for immediate usability in RelativityOne.

Applied in practice, these capabilities address common modernization needs.

Practical Applications

Built for enterprise-scale modernization, this expert-led service reduces risk, accelerates stakeholder buy-in, and protects evidentiary integrity—especially critical in time-sensitive investigations and post-merger integrations.

Platform Consolidation

Unify multiple Relativity Server instances into a single RelativityOne tenant— standardized, scalable, and defensible.

Tool Rationalization (Law Firms)

Replace patchwork review tools with a single platform; transparent reporting speeds stakeholder alignment.

Investigations and Regulatory Response

Maintain pace and precision in time-sensitive matters with strict chain-of-custody controls.

Post-Merger Integration

Phase consolidation across inherited hosting landscapes for measurable time-to- value.

These scenarios translate into measurable operational gains; the next section summarizes the benefits organizations typically realize.

Real-World Benefits

Retire legacy risk and cost while gaining elastic scale and integrated analytics. Vendor-reported results include up to four times faster processing and up to 80% reduction in review time with properly implemented Relativity aiR-enabled workflows; outcomes vary by data, configuration, and workflow.

These results are driven by a structured approach; the six stages below detail how migrations are executed.

  • Continuity
    Active reviews proceed with minimal downtime.
  • Predictability
    Fixed-fee options for defined scopes or time-and-materials for bespoke, multiphase programs.
  • Risk Reduction
    Comprehensive lineage documentation and QA packets suitable for judicial or regulatory review.
  • Performance and Scale
    Cloud resources and analytics available on day one.

"Defensible workflow is our north star… our validation regimen is built to withstand scrutiny—while minimizing downtime for active matters."

Six-Stage Migration Methodology

A six-stage path emphasizes validation and continuity from assessment through enablement, with rollbacks documented and cutovers calibrated to minimize disruption.

1

Readiness and Scoping

Inventory workspaces, custodians, data sources, configurations, and analytics artifacts; surface risks and dependencies.

2

Pilot Migration

Prove throughput and quality on representative matters; refine design and wave plan.

3

Wave Planning

Sequence matters using a proven status-based methodology to protect ongoing work – set cutover windows and rollback options.

4

Execution and Validation

Export/import with hashing, counts, targeted sampling, and exception management; remediate and record exceptions.

5

Cutover

Orchestrate calibrated transitions; confirm continuity for active matters; capture outcomes and exceptions.

6

Post-Cutover Enablement

Health checks, user/role mapping, targeted enablement for analytics and Relativity aiR – deliver documentation package.

Documentation and Coordination

Audit-ready artifacts that provide defensibility and operational readiness.

1

Matter-level runbooks and source-to-destination data lineage maps.

2

Validation and QA documentation with exception reporting.

3

Cutover summaries
(outcomes and exceptions).

4

Health-check report, user/role mapping, and analytics/aiR enablement notes.

With scope and outputs clarified, the availability and engagement models are as follows.
