IPv6 supports multiple concurrent addresses (from different prefixes), and can learn new ones or deprecate old ones over time. Attachment to a new network doesn't require renumbering, it requires propagating new prefixes for the hosts to use in addition to their existing ones. Primarily RFC6724 address selection will help the hosts choose the right addresses to use as source and destinations when they have multiple addresses.

Mark,

How does this help the medium-sized enterprise which has internal 
resources that need host names?
