A safe migration follows an order: inventory, pilot, operating rules, rollout, and only then advanced automation.

Quick answerStart with the highest-volume channel. Inventory accounts and owners, connect a pilot, validate sending and receiving, configure queues and permissions, train the team, and only then migrate the next channel.

Use this guide with a small sample of real conversations before changing a live workflow. Record the current owner, response path, handoffs, permissions, and reporting result. Then test one controlled change end to end, including failure and recovery. A tool decision is only complete when agents can follow the process and managers can verify the outcome.

Inventory before connection

For each channel, record the account, business owner, connection method, people with access, volume, operating hours, current automations, integrations, and retention requirements.

Include old numbers, aliases, and social pages that still receive customer contact. Hidden entry points create hidden backlog.

  • WhatsApp number and ownership
  • Instagram account and connected Facebook Page
  • Email inboxes, aliases, and sending identities
  • Website domains, widget, consent, and hours
  • Current integrations and fallback owners

Migrate in four controlled phases

First run a technical pilot and test real inbound, outbound, attachments, reconnection, and error reporting. Then run an operational pilot with a small team and real ownership rules.

Move the channel only after the pilot is stable. Declare one official inbox, preserve old history for reference, and document rollback. Consolidate procedures before connecting the next channel.

  • Technical pilot
  • Operational pilot
  • Controlled migration
  • Consolidation and next-channel rollout

Unify identity carefully

A person may contact you from a personal phone, work email, and social profile. Preserve every original channel identifier and merge only with reliable evidence.

Make identity changes traceable and reversible. Two temporary profiles are safer than exposing one customer's history to another.

  • Prefer exact verified matches
  • Ask for confirmation when ambiguous
  • Record who merged a profile and when
  • Allow incorrect merges to be separated

Validate the complete journey

A green connection status is not proof. Send a real message through every relevant path and confirm sender, timestamp, attachment, ownership, reply delivery, search, permission, and reporting.

For the first 30 days, review duplicates, old conversations, transfers, and reopened cases weekly. Improve the operating model before adding more automation.

Implementation checklist
  • Incoming and outgoing messages work on the real channel
  • Images, audio, and documents render correctly
  • Ownership and department persist
  • Transfers retain history and notes
  • Access rules are enforced
  • Search and reports include the migrated conversation
