Import data from one Slack workspace to another

Looking to merge two workspaces? Using Slack’s import and export tools, you can export member, message, and channel data from one workspace and import it to another.

Before you get started

Note: We don't support imports to Enterprise Grid organizations. As an alternative, you can import data to a separate workspace, then migrate that workspace to your org.


Understand your export options

If you’re on the free version of Slack or the Standard plan, you can use Standard Export. Customers on the Plus plan can use Standard Export, or apply for Corporate Export. See what's included in each export type in the lists below.

Standard Export
  • Public channels, including their messages and members
  • Links to files shared in public channels
  • Member profile information
Corporate Export
  • Public and private channels, including their messages and members
  • Direct messages
  • Links to files shared in channels and direct messages
  • Member profile information

Note: In shared channels, any links to files and their associated messages will only be included in your export if they were sent by a member of your organization.


Step 1: Export data from your origin workspace

To simplify your merge, we recommend exporting data from your smaller or less active workspace and importing it to your larger or more active workspace. Follow the steps below to export data:

  1. Follow our guide to download a copy of your workspace data.
  2. After you’ve downloaded your export file, sign in to the workspace you’ll be importing to.


Step 2: Upload your export file

Note: Modifying your export file in any way before uploading it may cause issues with your import. Once you've uploaded your file, you can choose which data to import.

  1. Upload your zipped export file to a secure cloud service, like Google Drive, Dropbox, or Box, and generate a public direct download link (make sure to keep this link handy). If you’d like, you can skip this step and upload the file directly when you reach step 5 below.
  2. From your desktop, click your workspace name in the top left.
  3. Select Settings & administration, then Workspace settings from the menu.
  4. Click Import/Export data. Next to Slack, select Import.
  5. Paste the link to your export file into the Direct download link field, or click Upload it directly and choose the zipped export file from your computer.
  6. Click Upload File.

You’ll get an email when the upload is done. From the email, click Continue your import to open the imports page, then click Next.


Step 3: Choose members to import

Now you’re ready to import members to your destination workspace.

Default member import options

Below are the default import options for different types of users. You can apply a batch action from the first drop-down menu you see or manually select a different option for an individual user before starting your import. You can view all member import options in our FAQ.

Note: If you select a batch action in the first drop-down menu, this will override any default or individual user settings.

User type Default import option
Users with a matching email address in the destination workspace Merge users
Active users without a matching email address Import just their messages
Deactivated users without a matching email address Import as deactivated
External users in a shared channel* Import just their messages

*External users will not be visible in the user import options and cannot be imported.

Note: Users cannot be imported as guests or merged into existing guest accounts. You can import guest users as deactivated full members, then reactivate them as guest users when the import is done.

Choose members to add

  1. Decide how to import users with a matching email address. You can click the first drop-down menu to choose a different option for all users, or click the arrow next to Show users to override the pre-selected import setting for individual users.
  2. Decide how you’d like to import users without a matching email. You can click the first drop-down menu to choose a different option for all users, or click the arrow next to Show users to override the pre-selected import setting for individual users.
  3. Click Next.


Step 4: Choose channels to import

You can merge any channel into an existing public channel. For privacy reasons, you can’t merge any channels with existing private channels or shared channels. Instead, a new channel will be created. You can view all channel import options in our FAQ.

Note: A batch action selected in the first drop-down you see will apply to all users, overwriting any defaults or individual channels’ settings.

Default channel import options

Channel type Default import option
Channels with the same name as a public channel in the destination workspace Merge channels with existing Slack channels
Public channels on origin workspace without matching names Create new public channel
Private channels on origin workspace without matching names Create new private channel
Archived channels on origin workspace without matching names Don’t import

Note: Any archived channels you choose to import will not be archived in your destination workspace. By default, archived channels will be set to Don’t import, but you can import them as regular channels and archive them when your import has completed.

Choose channels to add

  1. Decide how to import channels with a matching name. You can click the first drop-down menu to choose a different option for all channels, or click the arrow next to Show channels to override the pre-selected import setting for individual users.
  2. Decide how you’d like to import channels with no matching name. You can click the first drop-down menu to choose a different option for all channels, or click the arrow next to Show channels to override the pre-selected import setting for individual users.
  3. If your Corporate Export file contains private data and you want to import direct messages, check the box next to Direct Messages between imported users.
  4. Click Next.

Note: When channels are created during an import, a channel creator is included in each channel. As the person running the import, you may be added to channels and listed as the channel creator if the original channel creator is not being imported.


Step 5: Review summary and run import

  1. Review your import selections to make sure everything looks right. If you need to make any final changes to your import, click Edit. This will take you back to Step 4 in the import flow, where you can update channel data. To modify users, select Choose users to import. Click Next to return to the import summary.
  2. When you’re ready to import your data, click Import. You can use the progress bar to track the status of your import. You’ll also see Importing… next to data currently being moved into Slack.

Slack will run your import in five phases and send you an email when your import is complete.

Note: Members can use the destination workspace as usual while the import is running, but should avoid making any changes to channels or user accounts. Making these changes may cause the import to fail.
