A practical, timeline-driven checklist studios can use to archive, migrate, or transfer MMO assets and player data before shutdown—lessons from New World.

When an MMO is set to sunset, you have one shot to save player trust, legal compliance, and irreplaceable game history.

The recent announcement that Amazon’s New World will be taken offline on January 31, 2027 is a wake-up call for every studio running an MMO. Delisting, layoffs, and an extended maintenance mode left players and teams scrambling — and it showed how messy a shutdown can become when there’s no clear migration playbook. If you’re responsible for an MMO backend, this article gives you an actionable, timeline-driven checklist to archive, migrate, or transfer MMO assets and player data before shutdown.

“We want to thank the players for your dedication and passion… We look forward to one more year together.” — New World announcement, 2026

Why studios must treat shutdown like a data migration project

MMO shutdowns aren’t just server switches. They’re complex cross-functional migrations that touch engineering, legal, community, finance, ops, and store partners. Late-2025 and early-2026 industry events — mass studio layoffs, platform delistings, and vocal community reactions to games going offline — have made two things clear:

Players expect data portability and transparent timelines.
Regulators and payment processors demand documented retention, deletion, and export processes.

Start the migration as if you’re moving a living city: snapshot the infrastructure, package the social graph, and preserve the economy. Below is a practical, prioritized checklist and a recommended timeline tailored to late-2026/2027 realities.

High-level migration strategy (inverted pyramid)

Top priorities first: preserve player data and legal compliance, then protect digital goods and economy integrity, and finally prepare assets for transfer, community archives, or open-sourcing.

Preserve personal and account data for user requests, audits, and portability.
Secure virtual economies and item records to prevent fraud and maintain historical integrity.
Archive binaries, art, and content pipelines for potential transfer or community hosting.
Document system architecture, dependencies, and runbooks for future re-deployments or buyers.

Recommended timeline: what to do and when

New World’s public window gave the community roughly a year. Use the following windowed plan to prioritize tasks and communicate clearly.

Immediate (Day 0 – 30): Declare intent, freeze changes, and inventory

Public announcement & timeline — Publish a single source of truth (website + pinned forum post) with exact sunset date, purchase delisting info, and refund policy.
Code and infra freeze — Stop non-essential feature work and risky DB migrations. Only emergency fixes.
Full inventory — Create an exhaustive inventory: services, databases, queues, third-party vendors (anti-cheat, payments, CDN), certificates, secrets, asset buckets, and license agreements.
Legal & privacy assessment — Map GDPR/CCPA data types, retention obligations, and any subpoena/liability windows. Assign a data protection officer for export requests.
Assign roles — Define owners for Archive Lead, Export Lead, Ops Lead, Community Lead, Legal Lead, and Buyer Liaison.

Short-term (1–3 months): Export APIs, backups, and tamper-proof archives

Design data export APIs — Build user-facing exports (JSON/CSV/Parquet) for profiles, characters, inventories, transaction history, and guilds. Include timestamps and checksums.
Create canonical DB snapshots — Use logical exports (mysqldump/pg_dump with consistent snapshot settings) and point-in-time recovery (PITR) logs. For scale, use CDC (Debezium or native DB CDC) to stream changes into object storage for continuous replay.
Immutable storage — Store snapshots in WORM/immutable S3 buckets (or equivalent) with versioning and server-side encryption (SSE-KMS). Retain manifests and signed checksums for verifiability.
Preserve binary assets — Archive game builds, server binaries, archetype assets, shader caches, and raw art files. Include pipeline metadata (build IDs, engine version, compiler flags).
Record operational metadata — Export monitoring dashboards, alerting rules, observability dashboards, runbooks, onboarding docs, and capacity profiles (peak concurrent users, average latency metrics).

Mid-term (3–6 months): Test replays, package buyer offers, and protect the economy

Test restore runs — Rehydrate snapshots into a staging environment. Validate schema integrity, checksum verification, and sample player exports for data completeness.
Economy stabilization — Freeze or reduce risky monetization and trading windows. Introduce cooldowns, cap auctions, and limit currency faucets to prevent last-minute inflation/exploits.
Fraud prevention — Harden authentication (re-validate sessions), monitor unusual item transfers, and block suspicious accounts. Prepare a plan for forensic analysis of suspicious activity.
Buyer and community packaging — Prepare “for sale” packages: data room with architecture docs, cost model for hosting, and a set of licensing options (source code escrow, data transfer SLA, IP licensing or open-source release).
Third-party contracts — Negotiate transfer or termination with CDNs, payment processors, and anti-cheat providers. Ensure transferability clauses or escrow arrangements are clear.

Final stretch (6–12 months before sunset, and final 30 days)

Player exports go live — Activate the self-serve export portal. Rate-limit exports and provide status pages. Offer batch exports for power users and guilds.
Open-source and community options — If feasible, open-source server code under a license that allows community rehosting, or provide a server SDK and deployment templates (Docker, Helm charts, Terraform modules).
Escrow for buyers — Place source code and data in a trusted escrow with clear release conditions for bona fide buyers.
Communications cadence — Weekly community updates, FAQ expansions, and AMAs. Provide clear steps on what players can export and how to host community servers if supported.
Final billing & refunds — Close purchases, calculate refunds or store credit, and publish an FAQ on entitlements.

Shutdown day and post-shutdown (Day 0 to 90 post-sunset)

Controlled cutover — Redirect game clients to a maintenance page. Disable matchmaking, then gracefully drain servers. Take final consistent DB snapshot and freeze it to immutable storage.
Post-mortem & transparency — Publish a dataset manifest and an official audit log of exports and snapshots. Share timelines and any unresolved issues.
Decommissioning schedule — Define when credentials are revoked, when third-party contracts end, and the retention schedule for archived data.
Support window — Maintain a minimal support window (60–90 days) for export help and legal requests; extend if legal obligations require.

Detailed technical checklist (actionable items)

Below are concrete engineering tasks and recommended tech choices. Adapt to your stack, but don’t skip any category.

Data and database

Schema versioning: tag current schema in repo and export schema DDLs.
Export formats: JSON for nested player objects; CSV or Parquet for transactional logs; protobuf/Avro for binary efficiency.
CDC pipeline: set up Debezium/Kafka or cloud-native CDC to stream incremental changes into object storage for reproducible replay.
Encryption & signing: encrypt at rest (KMS) and sign manifests with an HSM key for provenance.
Consistency checks: run record counts, sample checksums, and reconcile tombstones (deleted items) to ensure accurate state.

Assets & builds

Archive raw art, audio stems, and high-res textures with file-level metadata and author credits.
Store build artifacts with container images (OCI registry), server binaries, and deployment manifests (Docker Compose, Kubernetes Helm charts).
Preserve licensing info for middleware (audio libraries, physics engines) — some licenses restrict redistribution.

Service topology & runbooks

Diagram service dependencies and ingress paths. Export observability dashboards (Prometheus rules, Grafana dashboards).
Include runbooks for common operational tasks: boot node, scale up, restore from snapshot, rotate keys.
Document capacity and cost metrics: peak CCU, average instances, bandwidth, and monthly cost per 1k CCU.

Legal, privacy & compliance

Map PHI/PII locations and anonymize where required (hashing with salt, irreversible deletions on request).
Offer data subject access exports (GDPR portability) in machine-readable form within legal windows.
Preserve transaction records for refund windows and tax audits, following local retention laws.

Community & storefront

Delist timeline: coordinate with Steam, Epic, console stores for delisting, refunds, and entitlements.
Community tools: provide tools for guild exports, forum archives, and in-game screenshot bundles.
Moderation archives: export chat logs and moderation history with redaction as needed for privacy.

Escrow, transfer, and open source — options & pitfalls

Studios often face three paths: sell to a buyer, transfer to a community team, or open-source parts of the stack. Each has tradeoffs.

Sale to buyer: Requires a clean data room, transferable contracts, and a negotiation on IP, third-party licenses, and ongoing liabilities. Buyers will want runbooks and a staging restore test.
Community transfer: Offer server SDKs, API keys, and deployment docs. Ensure anti-cheat and DRM constraints are handled; some vendors prohibit transfer.
Open-source release: Great for legacy preservation, but you must remove or relicense third-party middleware and identify security-sensitive secrets.

Real-world lessons from New World and 2026 trends

New World’s phased shutdown and public timeline gave players clarity but also exposed gaps — notably around refunds, last-minute economy abuse, and community frustration over tooling for exports. Use their case to make these practical improvements:

Start early: New World’s year-long horizon was generous; many titles get 30–90 days. Begin the inventory and legal mapping at first signs of decline.
Transparency matters: Scheduled updates and an export portal prevent rumor-fueled panic. Players respond better to steady, factual communication.
Test restores: Staging rehydration prevents data surprises and proves to buyers you can deliver a viable dataset.

Industry trends in 2026 emphasize portability and community stewardship. Cloud-native tooling and containerized backends make rehosting cheaper. Regulators have increased scrutiny on data portability since 2024–2025, and players now expect self-serve exports as standard. Studios that prepare for those expectations preserve reputation and reduce legal risk.

Advanced strategies for preserving virtual economies

Economies are the hardest thing to migrate credibly. Follow these advanced steps to maintain integrity:

Ledger-based exports: Export a tamper-evident ledger of all currency transactions (append-only, cryptographically signed) so community hosts can validate balances.
Freeze & reconcile windows: Introduce a final reconciliation period where high-value transactions are audited before the final snapshot.
Controlled re-issuance: If transferring to a new host, provide a controlled minting API for developers to import verified ledger snapshots rather than arbitrary balance edits.

Testing, validation & QA

Run random sampling of player exports against original DB to verify integrity.
Automate checksum validation and manifest comparison as part of a CI job.
Perform a dry-run transfer to a third-party infrastructure to validate the buyer package.

Communication and community psychology

Technical execution fails without good communication. Build trust with clear, repeated messaging and tools that give players control.

Publish a clear FAQ answering “What I can export?”, “How long will data be available?”, and “How to host my own server?”.
Provide in-game prompts linking to export tools and status pages.
Offer official support channels and a dedicated migration help desk for complex exports.

Post-shutdown stewardship and costs

Archiving isn’t free. Plan for storage costs, legal window retention, and occasional support. Estimate and publish an archive budget and expected access SLA for researchers or buyers.

Actionable checklist (printable, prioritized)

Publish sunset timeline & contact points.
Freeze non-critical releases; do full infra and dependency inventory.
Build user-facing export APIs and a self-serve portal (JSON/CSV/Parquet outputs).
Create immutable DB snapshots + CDC log stream to object storage (S3/Blob) with KMS encryption.
Archive binaries and asset master files; document build & pipeline metadata.
Test restore into staging environment and validate player samples.
Stabilize economy: freeze risky flows, add caps and cooldowns.
Negotiate third-party transfers or terminations; prepare escrow if selling.
Enable community options: server SDK, deployment templates, or open-source plan.
Execute controlled shutdown, final snapshot, and public audit of exports.

Final thoughts

Sunsetting an MMO is one of the most sensitive operations a studio can perform: millions of social connections, hours of player time, and complex economies are at stake. The New World timeline in 2026 showed that clarity, technical readiness, and community-first tools reduce friction and preserve value — whether that value goes to a buyer, a community host, or the historical record.

Start today: run the inventory, assign the leads, and publish the timeline. The cost of delay is reputational damage, legal exposure, and irreplaceable loss of player data.
