Transfer A Meeting from One Host to Another?

Can you please clarify whether you need to transfer the meeting between users on the same paid account (ex: user1[at]xyz[dot]com to user2[at]xyz[dot]com ) or between users on different Zoom tenants (ex: user1[at]xyz[dot]com to user1[at]abc[dot]com )?

The first scenario is entirely possible, albeit a multi-step process. "Changing Host of a Reoccurring Meeting as an admin" 

The second scenario is not possible as an admin, but may be a maneuver that a Tier II/III/+ Zoom Support agent can assist you with if you're able to prove ownership of both paid Zoom tenants.
