Can we change from an Hourly Interacting license type to a Concurrent or a Named license type?

Yes. You can change a user’s license type from Hourly Interacting to Named or Concurrent. To make this change, an Administrator can remove the Billing > User > hourlyInteracting permission from a user’s role.

Note: Users who have administrative or supervisory permissions are not eligible for hourly interacting metering. For more information, see Hourly interacting license disqualifying permissions.

When the change becomes effective, measurement for the usage of the new license type is retroactive to the beginning of the current billing period.
