When Platforms Shut Down: A Migration Playbook for Domains, DNS and VR-Style SaaS

When platforms shut down: a migration playbook for domains, DNS and VR-style SaaS

Hook: Platform sunsets are the silent crisis modern website owners and small teams face in 2026 — from micro-apps to Meta’s Workrooms closure, services disappear quickly and can take your domains, DNS or customer-facing integrations with them. This playbook gives you a step-by-step, battle-tested plan to migrate safely: inventory, export, adjust DNS TTLs, prepare redirects, and validate every step so traffic, email and SEO survive the switch.

Why this matters now (2026 context)

In late 2025 and early 2026 the tech industry accelerated consolidation and product pruning. Meta announced the shutdown of the standalone Workrooms app on February 16, 2026, citing a strategic shift into other Reality Labs initiatives and Horizon-managed capabilities. That public example is a wake-up call: even large platforms sunset products suddenly and at scale.

At the same time, the rise of micro apps — quick, personal or team apps built in days with AI tooling — has increased the number of ephemeral services that may be retired without long-term support. For anyone who uses third-party SaaS (especially VR/AR collaboration tools), the risk of a sudden service sunset is higher today than in previous years.

"Make service sunsets a planned part of your architecture: assume any third-party integration can vanish and design migrations as an expectation, not an emergency."

Inverted-pyramid summary: What to do first (top-level checklist)

1. Inventory everything tied to the platform (domains, DNS zones, webhooks, data exports, SSL keys, email routing).
2. Export all records, assets and logs — zone files, meeting exports, database dumps, attachments.
3. Lower DNS TTLs well ahead of switch to speed propagation.
4. Prepare target infrastructure (new DNS host, new app hosting, redirect endpoints, certificates).
5. Switch nameservers or records in controlled steps with monitoring and rollback points.
6. Execute redirects (301s for SEO-critical moves) and validate.
7. Monitor & document — keep logs, timelines, contacts for audit and troubleshooting.

Case study: Meta Workrooms shutdown (what we learned)

Meta communicated that Workrooms would no longer be supported as a standalone app on Feb 16, 2026. Organizations that used Workrooms for internal collaboration or customer events needed to extract data and find alternate VR/AR tools or fall back to 2D conferencing. Key takeaways:

• Large vendors can announce sunsets with short lead times tied to broader strategy shifts.
• Managed services (like Horizon managed services) can be discontinued even when hardware (Quest headsets) remains supported — plan separately for hardware and service lifecycles.
• Always assume platform exports may be limited; prioritize exporting the most valuable artifacts first (logs, recordings, membership lists).

Step-by-step migration playbook

1) Inventory and impact mapping (Day 0–3)

Before clicking anything, create a precise inventory. Use a spreadsheet or your domain management tool to capture:

• Domains and subdomains hosted on the platform
• DNS providers and nameserver configuration
• Active records: A, AAAA, CNAME, MX, TXT, SRV, NS, PTR, TLS/SSL setup
• Email flow and IMAP/POP access points
• API keys, webhooks, OAuth redirects, and integrations
• Data that must be exported (meeting recordings, attachments, user lists)

Output: an actionable map of what must be moved, and dependencies that must remain live during migration (e.g., mail servers).

2) Export everything you can (Day 1–7)

DNS/Zone export: Export zone files or record lists from the platform. Most providers support a zone file export or API endpoint:

• Cloudflare: API export - GET /zones/:zone_id/dns_records/export
• AWS Route 53: aws route53 list-resource-record-sets --hosted-zone-id Z123
• Google Cloud DNS: gcloud dns record-sets export
• cPanel: Zone Editor > Export
• If the provider supports AXFR: dig @ns1.example.com example.com axfr

Application data and assets: Export meeting recordings, logs, user lists, and attachments. Prioritize the most business-critical exports first — you may not get unlimited time.

Email: Back up mailboxes using IMAP sync tools (isync/mbsync or imapsync) and export mailing lists. Make sure SPF, DKIM and DMARC records are captured.

Certificates and keys: If you control private keys (rare with managed certs), export them securely. If you use managed certs, plan to reissue on the target host (Let’s Encrypt or your CA).

3) Prepare the destination (parallel)

Set up the new DNS host and replicate the exported zone. Before you change anything live, verify the new DNS responds correctly on a staging domain or by forcing lookups.

• Create identical A/AAAA/CNAME records and MX, TXT records for mail.
• Provision TLS/SSL on the new host — use DNS-validated certificates if you’re changing nameservers.
• Set up email routing and test mailbox logins.
• Deploy a minimal web origin that returns valid HTTP status codes for redirects or content validation.

4) Lower DNS TTLs well ahead of the switch (48–72+ hours before)

Why: Lower TTLs reduce caching and speed up propagation of record changes so rollouts and rollbacks are quicker.

How: At least 48–72 hours before a planned switch, set the TTL for critical records (A, CNAME, MX) to 300 seconds (5 minutes). For very large infrastructures, reduce TTLs 72+ hours before.

Notes:

• Lowering TTLs itself must propagate, so do it early.
• Some providers enforce minimum TTLs; document any limits.
• After migration stabilizes, raise TTLs back to 3600–86400 to reduce query volume.

5) Plan your switch (DNS nameserver change vs record update)

Two common strategies:

1. Switch nameservers: Change registrar NS records to point to the new DNS host. Good for moving entire zones, but slower to propagate and riskier if you miss records.
2. Update individual records: Modify only the records that need changing (A, CNAME, MX). Safer if only web or API endpoints move.

Choose the approach based on scope. If moving the whole zone, nameserver change is cleaner — but ensure your new DNS host contains every record from the exported zone (including subdomain records and TXT entries used for verification).

6) Redirect strategies that preserve SEO and user experience

For domain-level moves: Use 301 redirects from old URLs to new URLs to preserve link equity. For temporary moves, use 302 but switch to 301 after stabilization.

How to implement redirects:

• Edge/CDN: Use Cloudflare Workers, Fastly, or your CDN’s edge logic to create global redirects with low latency and full control.
• Origin web server: Implement 301s at the webserver (Nginx, Apache) for full control and header handling.
• Registrar/host forwarding: Quick but limited — often no path preservation and poor SEO handling. Avoid for complex redirects.

Preserve query strings and headers: Ensure your redirect logic preserves query strings for campaign tracking and referral integrity.

Canonical & hreflang: Update canonical tags and hreflang links on destination pages to reflect the final domain to avoid duplicate-content issues.

7) Email and deliverability continuity

Mail is often the largest invisible casualty. Before switching DNS:

• Copy SPF, DKIM and DMARC records exactly to the new DNS host.
• If you change MX records, keep old MX live for a graceful handover (or use parallel delivery if supported by your mail provider).
• Export mailboxes with imapsync to the new provider; confirm new mailboxes receive messages.

8) SSL/TLS and session continuity

Reissue TLS certificates on the destination early. If you used a managed cert that cannot be exported, provision a new cert using DNS or HTTP validation. If user sessions depend on domain-specific cookies, plan a session invalidation and re-login window.

9) Cutover, immediate checks and rollback plan (Day X)

Execute cutover during a low-traffic window. Steps:

1. Confirm backups and exports are safe and accessible.
2. Apply DNS changes (or update nameservers).
3. Monitor propagation using multiple recursive resolvers (Google 8.8.8.8, Cloudflare 1.1.1.1, your ISP).
4. Check key pages, assets, and email delivery. Use synthetic tests and a real-user check group.
5. If issues appear, rollback by restoring the previous records or re-pointing nameservers — keep rollback steps scripted for speed.

10) Post-migration hardening (Day +1 to +14)

• Raise TTLs back to normal values after 48–72 hours of stability.
• Re-enable DNSSEC if used (re-sign zones after nameserver or key changes).
• Update WHOIS contact info and ensure WHOIS privacy is set as desired.
• Document every change, timestamps, and contacts for audits.
• Run SEO checks: index status, sitemap submissions, check for crawl errors in Search Console and Bing Webmaster Tools.

Special considerations for VR-style SaaS and ephemeral apps

Use Meta Workrooms as a real-world example: assets may include meeting recordings, avatars, custom scenes, and user lists. For VR/AR platform shutdowns:

• Export recordings and media in the native formats you can reuse elsewhere.
• Capture participant lists and permission mappings for re-creation in alternative tools.
• Document integration points — which APIs were used for single-sign-on, which webhooks powered notifications.
• For headset-managed services (e.g., fleet management), separate hardware lifecycle tasks from service migration.

Operational templates: quick commands & examples

Export Route 53 zone

aws route53 list-resource-record-sets --hosted-zone-id Z123ABC > zone-records.json

Cloudflare API export

curl -X GET "https://api.cloudflare.com/client/v4/zones/{zone_id}/dns_records/export" \
 -H "Authorization: Bearer $CF_API_TOKEN" -H "Content-Type: application/json"

AXFR (if allowed)

dig @ns1.example.com example.com AXFR

Checklist: what to capture in your migration log

• Date/time of every change (UTC recommended)
• Records changed and previous values (very literal copies)
• Who authorized the change and contact info
• Backups and export file locations with checksums
• Rollback commands and who is on-call

Risk profile & mitigations

Common risks and how to mitigate them:

• Lost exports: Save copies off-platform and verify integrity with checksums.
• Propagation delays: Lower TTLs early and use staged cutovers.
• Email downtime: Keep old MX live in parallel and migrate mailboxes ahead of time.
• SEO loss: Always use 301s for permanent moves, update sitemaps, and monitor Search Console.
• Authentication breakage: Re-establish OAuth redirects and regenerate client secrets early.

Future-proofing: what to change in your architecture

Design for graceful exits:

• Prefer standards-based integrations over proprietary formats where possible.
• Keep independent backups of content and user data (exportable formats like CSV, MP4, JSON).
• Keep domain and DNS control at a registrar you trust and enable 2FA and account recovery options.
• Use Infrastructure-as-Code for DNS and hosting definitions so you can reconstruct environments quickly.

Key takeaways

• Assume sunset: Build migration ability into your vendor strategy in 2026 — platform shutdowns are increasingly likely.
• Act early: Inventory and export immediately; lower TTLs well before a planned cutover.
• Preserve SEO & email: Use 301 redirects and parallel mail flows to avoid losing traffic or messages.
• Document & automate: Keep a migration log and script rollback steps.

Resources and templates

Use your registrar’s support docs for EPP/Auth code and domain transfer rules. Keep a folder with:

• Zone file exports
• IMAP mailbox exports
• OAuth client IDs and redirect URIs
• Sequence of cutover commands and automation scripts

Final thoughts: treat sunsets as planned events, not surprises

Meta’s Workrooms closure in early 2026 is a practical reminder that even large platforms reprioritize quickly. The organizations that navigated it best were the ones that had an export-first mindset, assumed short lead times, and treated DNS + domain ownership as critical assets, not incidental settings.

Actionable takeaway: Right now — run a 30-minute audit: list every domain you control, export DNS zones, and set TTLs to 300 for any records you might need to change. Do that before you hear about the next sunset.
