Data Import and Migration

Data Import and Migration — CometChat documentation.

Data import and migration enables you to transfer existing chat data from your own servers or another chat provider to CometChat. This ensures continuity of service and preserves your users’ conversation history during the transition.

What Can Be Migrated?

CometChat’s migration capabilities cover:

• Users: User profiles, metadata, and account information
• Messages: Complete message history including text, media, and metadata
• Groups: Group configurations and membership information
• Conversations: Conversation threads and their associated data

Migration Approaches

CometChat offers two approaches to data migration, depending on your needs:

Historical Data Import

Import all your existing data at rest—stored messages, users, and groups—into CometChat before going live. This approach is ideal when:

• You’re doing a complete platform switch
• You want all historical data available from day one
• Your migration can happen during a maintenance window

The Data Import APIs handle bulk ingestion of historical chat data, allowing you to transfer large volumes of users, messages, and group information efficiently.

Live Data Migration

Maintain communication between users on your old system and users who have already migrated to CometChat. This approach is ideal when:

• You need zero downtime during migration
• Users will upgrade to the new app version gradually
• Seamless communication must continue throughout the transition period

Live migration bridges both systems during the upgrade cycle, ensuring no messages are lost regardless of which system a user is currently on.

Getting Started

For Historical Data Import: Use the Data Import REST APIs to programmatically import your users, messages, and groups.

For Live Data Migration: Contact our Sales team to discuss your migration requirements and set up the live migration process.
