Step-by-Step Slack Migration Simplified

1. Export Your Slack Data

To begin, export your data from Slack by accessing the Slack admin console. Log in to Slack and navigate to Workspace settings > Email address display > Expand. Enable Display members’ email addresses and click Save. Once email accounts are displayed, follow Slack's instructions to export your data.

2. Upload files to Lark

After exporting your data from Slack, it's time to upload it to Lark. Visit the Lark Admin Console, click on Settings, then Data Migration, and select Import from Slack. Choose Upload files and proceed to the next step.

Notes:

  • Only ZIP files smaller than 2 GB can be uploaded. For larger files, contact us for assistance.

  • Free and Pro plan users of Slack cannot export private channels and direct messages. Upgrade to Business+ or Enterprise Grid plans or contact Slack support for these options.
