OAT and Trasfers of Inventory and FA across Legal entity

Can anyone tell me what can/should happen if a transfer of inventory, which is tied to an FA record via Asset Tracking, is done via internal Sales Orders and is across legal entities?  I do not think OAT will do the retirement and addition auto-magically, but curious of what should happen, assuming all set-ups arte correct and proper steps are taken in order.  For example, Company A employs submits an internal req for Item XYZ, Company B creates/imports internal Sales Order to Company A for Item XYZ, and ships serial number B-1 which is associated to FA record 123.  Upon
