Federal + DoD-specific migration considerations
FedRAMP High tooling
Every migration tool must be FedRAMP High authorized for GCC-High deployment. Commercial-only tools are non-starters.
Data residency boundary
All project schedules, resource pools, timesheets, and audit logs must remain within the GCC-High boundary. No cross-cloud staging.
CJIS + IRS 1075 audit trail
Immutable audit log preservation for 7+ years, chain-of-custody attestation, WORM storage policy on export destination.
Tenant status now
Microsoft publishes no GCC High or DoD extension. Confirm your tenant's current access with your Microsoft account team before planning around data that may no longer be reachable.
4-Phase Federal Migration Engagement
Phase 1 — Discovery (2 weeks, fixed-fee)
Current tenant assessment, GCC vs GCC-High vs DoD residency validation, feature parity gap analysis, active-project inventory, cutover risk model, fixed-fee proposal.
Phase 2 — Foundation (4-6 weeks)
Planner Premium tenant configuration, migration tool FedRAMP High validation, security hardening, pilot with 1-2 low-risk projects, training curriculum.
Phase 3 — Rollout (6-12 weeks depending on portfolio)
Batched migration (20-50 projects per wave), user training delivery, cutover to read-only source, active support during the transition window.
Phase 4 — Attestation (2-4 weeks)
Post-migration audit-trail package for CJIS / IRS 1075 review, tenant hardening, sustaining-services handoff to managed operations.
Federal Project Online Migration FAQ
Is Planner Premium available in GCC and GCC-High?
Yes. Microsoft confirmed Planner Premium availability in GCC and GCC-High tenants, with a rollout that trails commercial by approximately one quarter. Federal customers should validate specific feature parity (Copilot in Planner is gated separately in gov clouds). EPC Group has migrated multiple federal / DoD tenants and can validate feature availability at engagement start.
What was the Project Online retirement date for government tenants?
Microsoft retired Project Online on September 30, 2026. Microsoft's retirement notice and the Learn lifecycle page name one date, no separate GCC, GCC High or DoD timeline, and no extension. Confirm your tenant's current status with your Microsoft account team; EPC Group does not assert an extension it cannot source.
What is different about the GCC-High migration?
GCC-High migrations differ in four ways: (1) Data residency — all data (project schedules, resource pools, timesheets, audit logs) must remain in the GCC-High boundary, (2) Identity — GCC-High uses a separate Azure AD tenant with no cross-tenant federation to commercial, (3) FedRAMP High baseline — every migration tool must be FedRAMP High authorized, (4) Audit trail — CJIS or IRS 1075 environments require immutable audit logs preserved for 7+ years post-migration.
What migration tools work in GCC-High?
FedRAMP High authorized migration paths for Project Online → Planner Premium: (a) Microsoft native migration (Assistant tool) — FedRAMP High authorized for GCC-High, (b) EPC Group custom migration scripts (Graph API + PSA integration) — FedRAMP High readiness available at request, (c) Third-party ISVs (validate FedRAMP High authorization before selection — a common mistake is picking a commercial-only tool). Do NOT use any tool that lacks explicit GCC-High authorization.
What is the CJIS / IRS 1075 audit path?
CJIS-regulated projects (law enforcement schedule/task data) must preserve chain-of-custody through migration. IRS 1075 (federal tax administration) has similar strict-audit requirements. Path: (1) Freeze Project Online in read-only mode 30 days pre-cutover, (2) Export full audit log via PowerShell + Graph API to immutable Azure Blob storage (WORM policy), (3) Preserve hash chain (SHA-256) of exported audit data, (4) Migrate active project schedules only — leave historical/closed projects in a read-only archive tenant, (5) Post-migration, generate audit-trail attestation letter for CJIS / IRS 1075 review.
What is EPC Group's federal Project Online migration methodology?
Four-phase engagement: (1) Discovery — 2-week paid workshop assessing current tenant, GCC vs GCC-High vs DoD residency, feature parity gaps, active-project inventory. (2) Foundation — Planner Premium tenant configuration, migration tool selection + FedRAMP validation, pilot with 1-2 low-risk projects. (3) Rollout — batched migration of active projects (typically 20-50/wave), user training, cutover to read-only source. (4) Attestation — post-migration audit-trail package for CJIS / IRS 1075 review, tenant hardening, sustaining-services handoff. Senior architect leads every phase — no offshore hand-off.
