The tenant to which the user belongs can be changed by moving the user with swcfmg_account (refer to "swcfmg_account (User Information Management Command)" in the Reference Guide for details).
If the user is an L-Platform owner, the tenants that belong to that L-Platform will not change. One of the actions below must be performed when moving a user:
Before moving the user, change the ownership of their L-Platform to one of the current tenants.
Refer to "Changing an L-Platform Owner" for details.
After moving the user, move the L-Platform owned by that user to a tenant at the destination.
Refer to "Moving an L-Platform" for details.
