[Data-modeling] How to move types to a new domain?

[Will Moffat]

Dear metaweb,

Mike Love and I would like to move 2 types from his default_domain to  
a new domain:

Types:
/user/mikelove/default_domain/influence_node
/user/mikelove/default_domain/peer_relationship

Old domain: http://www.freebase.com/view/domain/user/mikelove/default_domain
New domain: http://www.freebase.com/view/domain/user/mikelove/influence

How can we do this?
Can it be done without breaking existing apps?

regards,
--Will
