In cross-platform channels, Mio currently supports the lowest maximum membership limit of the platforms that you choose to sync. 

For instance, if you use Mio to sync your Slack and Webex groups, and your Slack channel has a limit of 5,000 members, and your Cisco Webex channel has a limit of 2,000, we'll stick with the 2,000 limits. 

If you have a Slack channel with more than 5,000 members, or you're syncing Slack with Microsoft Teams and have a channel with more than 2,500 members, you'll need to discuss your options with the Mio support team.
