Move a meeting from a basic to a separate licensed account

That's possible if both users are under the same account. But both needs to be licensed users.

You can edit meetings and change the host as many times as needed before the session starts. Any changes to the meeting while the meeting is active will not be reflected until the meeting is restarted. 

1. Sign in to the Zoom web portal.
2. In the navigation menu, click Meetings.
3. Find and click on the topic of the meeting you need to adjust. 
4. Click Edit. 
5. In the Schedule For section, click the drop-down and select a new host. 
   Note: You must already have scheduling privilege for both the current host and the user you wish to assign this meeting to. 
6. Click Save. 

Once the meeting is transferred between users on the Zoom web portal, the meeting should now appear on the list of upcoming meetings for the new host on the Zoom web portal, desktop client, and mobile app. If the event was exported to or scheduled directly in a calendar service, such as Outlook or Google Calendar, please make sure the new host has also been invited to the calendar event. 

Note: This is also possible with webinars, but requires all users (both hosts and the user with scheduling privilege) have the webinar add-on.
