A practical migration checklist and flowchart for IT admins decommissioning collaboration platforms—covers exports, SAML/SCIM provisioning, integrations, and continuity.

When a collaboration platform dies: your practical migration checklist and flowchart

Hook: You just learned an important collaboration platform your teams rely on is being discontinued (Meta’s Workrooms shutdown in early 2026 is the latest example). Now you face frantic export requests, broken automations, and questions from executives: what stays, what moves, and how do we keep business continuity?

Executive TL;DR (start here)

Prioritize continuity: Identify mission-critical data and integrations within 48–72 hours.
Export everything (messages, files, recordings, metadata, configs) to immutable storage with retention tags.
Re-provision users into the replacement platform using SCIM, SAML/OIDC or staged CSV imports — rotate credentials and decommission service accounts safely.
Map integrations (bots, webhooks, CI/CD, calendar, SSO) and move incrementally; respect API rate limits and compliance holds.
Communicate clearly with impacted teams, legal, and security — publish a recovery SLA and rollback plan.

Why this matters in 2026

Late 2025 and early 2026 saw several platform deprecations and consolidations. Vendors are trimming niche collaboration products while enterprises consolidate on platforms that support open export formats and standardized identity flows. The Meta Workrooms shutdown in January 2026 is a live example: organizations that had no export-first plan scrambled to preserve VR meeting artifacts and integrations. In this environment, exportability, identity portability (SAML/SCIM/OIDC), and integration portability are non-negotiable.

"Meta has made the decision to discontinue Workrooms as a standalone app, effective February 16, 2026." — company notice summarized by The Verge, Jan 2026.

Overview: the migration flow — high level

Use this flow as your canonical migration path. Start with assessment, then export, then reprovision, then integrations and decommission. Each step has checkpoints to protect data, access, and continuity.

The practical, step-by-step migration checklist

Below is a granular checklist you can paste into a ticketing system or runbook. Assign an owner and target date for each item.

Phase 1 — Rapid assessment (0–72 hours)

Inventory assets: Catalog users, teams, channels, files, recordings, bots, calendars, SSO/SAML configuration, SCIM provisioning endpoints, webhooks, and custom apps.
Tag mission-critical items: Identify assets required for legal holds, compliance, billing, or essential workflows.
Export policy check: Verify vendor export tools, rate limits, API quotas, and known shutdown deadlines.
Stakeholder map: Notify legal, security, platform engineering, finance, and team leads. Assign an executive sponsor.

Phase 2 — Data export & archival

Export is the most time-consuming step. Treat exports as a product: plan for retries, partial failures, and consistency checks.

Export scope: messages, attachments, revision history, meeting recordings, whiteboards, permissions, and channel membership lists.
Preferred formats: JSON for metadata, CSV for simple tables (users, memberships), ZIP/TAR for attachments, and MP4/WebM for recordings. Use EML/PST for email-like export if supported.

Automate exports: Use vendor APIs with pagination and incremental tokens. Example curl pattern (replace placeholders):

curl -H "Authorization: Bearer $API_TOKEN" \
  "https://api.OLDPLATFORM.example.com/v1/exports/messages?start=2025-01-01&format=json" \
  -o messages_page1.json

Preserve metadata: Export timestamps, original file names, SHA256 checksums, and permission metadata to support audits and rehydration.
Immutable storage: Put exports into object storage (S3/GCS/Azure Blob) with versioning and object lock when required by compliance. Add lifecycle rules for staged deletion if policy allows.
Catalog and index: Create a manifest (CSV/JSON) listing export files, contents, checksums, and retention tags. Index text content for search (Elasticsearch/Opensearch) for quick retrieval.

Phase 3 — User reprovisioning and identity

Identity is the backbone of a migration. Prioritize automated, auditable reprovisioning.

Choose target identity model: SAML 2.0 + SCIM is the enterprise standard; OIDC is common for modern cloud apps. If your replacement platform supports SCIM, use it for automated user and group sync.
Export identity data: Export user attributes, group memberships, roles, MFA status, and service accounts. CSV example fields: user_id, email, display_name, groups, role, created_at.

SCIM bulk provisioning: If supported by the new platform, map attributes and run a dry-run. Example SCIM create request (pseudo):

POST /scim/v2/Users
Authorization: Bearer $SCIM_TOKEN
{
  "userName": "jane@example.com",
  "name": {"givenName": "Jane","familyName": "Doe"},
  "groups": ["eng-core","admins"]
}

SAML/SSO: Exchange SAML metadata between IdP and SP. Verify assertion attributes (email, uid, groups). Rotate IdP certificates after cutover.
1. Export SAML metadata from the old SP if needed (for auditing).
2. Import SP metadata into the IdP for the new platform.
3. Test single-user SSO, then test group-based access.
Service accounts & tokens: Identify long-lived tokens and bots. Recreate tokens in the new platform and rotate the old ones. Store credentials in a secrets manager (HashiCorp Vault, AWS Secrets Manager).
Session handling: Notify users of required sign-outs and planned SSO freezes. Provide a help desk runbook for SSO issues.

Phase 4 — Integrations, bots, and automation

Integrations often break silently. Treat them as first-class migration items.

Map integrations: Create a matrix: integration name, owner, API endpoints, credentials, dependencies, criticality, replacement support.
Webhook migration: Replace platform-specific webhooks with intermediary adapters when the replacement platform uses different signatures or payloads. Use a translation layer (small serverless functions) to avoid touching many producers at once.
Bot migration: Re-register bots with the new platform, adjust scopes and tokens, and verify rate limits. Log bot traffic during dual-run to validate behavior.
CI/CD & infra ties: Update pipeline steps that interact with the old platform (notifications, deployments, approvals). Test in isolated branches before production cutover.
Calendar & presence: Migrate calendar integrations and test meeting creation, invite flows, and recording triggers.
Third-party apps: Check vendor support for the new platform. If unavailable, plan to replace functionality with in-house tooling or alternate vendors (consider Matrix, Mattermost, or open-source options for portability).

Phase 5 — Testing and validation

Functional tests: Validate messages, file access, role enforcement, and search across representative accounts.
Security tests: Re-run SSO assertions, check SCIM provisioning logs, and scan for leaked credentials in exported artifacts.
Performance and rate limit tests: Ensure the new platform handles expected traffic and integration bursts.
User acceptance (UAT): Run a dual-run period where both old and new systems operate concurrently for critical teams.
Audit trail: Ensure audit logs from the original platform are archived and accessible for legal/compliance needs.

Phase 6 — Cutover, monitoring, and rollback

Staged cutover: Move non-critical teams first, then business-critical groups during low-traffic windows.
Monitoring: Track delivery rates, auth failures, error budgets, and ticket volume closely for 72–168 hours post-cutover.
Rollback plan: Keep the exported data and a documented rehydration process. Define clear rollback criteria (e.g., >X% message failures or security incidents).

Phase 7 — Decommission

Revoke access: Revoke API keys, OAuth client secrets, and SAML certificates from the old platform once the cutover is finalized.
Preserve records: Maintain the exported manifest, audit logs, and checksums for the retention period required by policy.
Post-mortem: Document lessons learned, update runbooks, and publish a migration playbook for future decommissions.

Mapping permissions and roles — a short template

Permissions often don’t map 1:1. Use this simple matrix to document mapping decisions.

Old Role: Channel Admin —> New Role: Workspace Moderator (map channel scope to workspace where possible).
Old Role: Guest —> New Role: External Collaborator (limit file access and mentions).
Old Role: Org Admin —> New Role: Org Owner (ensure SCIM maps groups and privileges carefully).

Compliance, legal holds, and retention

Legal and compliance change the migration timeline. Always surface holds and preservation requests early.

Preserve immutable copies: Export and lock artifacts for any litigation or regulatory holds.
Metadata fidelity: Ensure timestamps, sender info, and channel membership are preserved.
Retention policies: Translate old retention rules into new platform policies where possible, and document exceptions.

Advanced strategies and 2026 trends to leverage

Use these advanced tactics to reduce future migration risk and align with trends in 2026.

Export-first architecture: Design integrations that persist important business data in your own systems (event-sourcing) instead of relying solely on vendor storage.
Diagrams-as-code: Store network and workflow diagrams in version control (e.g., Mermaid or PlantUML) and embed them into docs for easy rehydration. Diagrams stored as code are easier to migrate and re-embed into new platforms.
Adapter layers: Build a thin adapter layer for webhooks/bots so you can switch downstream platforms with minimal producer changes.
Open protocols: Favor platforms supporting Matrix, ActivityPub, or standard APIs to reduce vendor lock-in.
Zero trust identity: Consolidate to a central IdP with SAML/OIDC and SCIM to simplify multi-platform provisioning.

Mini case study: How a mid-size SaaS company migrated off a discontinued VR workspace (anonymized)

Background: A 400-employee SaaS firm used a VR collaboration app heavily for design reviews and recorded meetings. The app announced discontinuation with a 6-week window.

What they did fast: Within 48 hours they exported all meeting recordings and whiteboard sessions to S3 with versioning, created a manifest, and paused all scheduled meetings.
Identity: They re-provisioned users into the replacement platform using SCIM, mapping groups and roles programmatically (reduced manual work by 85%).
Integrations: Bots were re-registered and run through an adapter layer; calendar invites were switched to work with standard iCal hooks.
Result: Minimal business disruption, and the company retained searchable archives of the VR sessions. Post-mortem updated runbook reduced future migration time by 60%.

Common gotchas and how to avoid them

Missing metadata: Always request or extract metadata. Files without metadata are difficult to place in context later.
Service account surprise: Long-lived tokens used by CI may be overlooked. Search code repos and secrets managers early.
Rate limits: Vendor APIs will throttle exports. Plan time and use backoff/retry strategies.
Mapping mismatches: Role and permission gaps cause access issues post-cutover. Run a permissions audit before cutover.

Tooling checklist: scripts, storage, and monitoring

Export scripts (Python/Node) with pagination, backoff, and checksum verification.
Central object storage with lifecycle policies (S3/GCS + object lock when required).
Secrets manager for new credentials (Vault, AWS Secrets Manager).
Search index for exported text (OpenSearch/Elasticsearch) and a basic UI for legal retrievals.
Monitoring dashboards for auth failures, API errors, and migration progress (Grafana/Datadog).

Checklist you can copy into your runbook (condensed)

Inventory & categorize assets (72h).
Export data (messages, files, recordings, metadata) to immutable storage.
Catalog exports and verify checksums.
Export identity data and map to SCIM/SAML/OIDC schemas.
Recreate service accounts, rotate secrets, and store credentials securely.
Map and migrate integrations; use adapter layer for webhooks/bots.
Run tests: functional, security, performance, and UAT.
Execute staged cutover, monitor, and keep rollback triggers ready.
Decommission: revoke keys, preserve audit trail, and run post-mortem.

Final recommendations — reducing future risk

Document everything: Runbooks, export manifests, and mapping matrices are invaluable.
Automate exports: Schedule infra-level exports for critical data so future vendor changes don’t cause panic.
Favor open formats: JSON/CSV/MP4/TAR over proprietary blobs where possible.
Treat integrations as replaceable: Wrap them in adapters and keep the integration contracts minimal and well-documented.
