Group channel member limit increase

[Question]
We’re using Group Channels for discussions, but some have reached the 100-member limit, and we can’t add more users.
Can this limit be increased beyond 100, or is migrating to a Super Group Channel the only option?

If migration is required:

  • Is there any efficient or bulk way to migrate existing Group Channels to Super Group Channels, instead of recreating them one by one?

  • How can we retain or migrate past messages and data (message history, metadata, unread counts, etc.) during this process?


[SDK Version]
@sendbird/chat v4.9.11


[Current Impact]
We’re unable to add new members to active discussions, and manual migration would be time-consuming given the number of existing channels.

Hi @mbs,

The maximum member limit for a group channel is 100. This is why you were unable to add more members to the channel.

To add more members, you can convert the group channel to a supergroup channel. This can be done easily through the Dashboard by selecting the “Change to Supergroup” option, as shown below:

Alternatively, you can accomplish this using the Platform API by setting the `is_super` flag to true in the “Update a group channel” API request.

However, please note that some features are not supported in supergroup channels. You can find more information about this in the link below:
