Amazon CloudFront announces new APIs to locate and move alternate domain names (CNAMEs)

Amazon CloudFront announces two new APIs, ListConflictingAliases and AssociateAlias, that help locate and move Alternate Domain Names (CNAMEs) if you encounter the CNAMEAlreadyExists error code. These new APIs let you see which distribution has the CNAME and move the CNAME to a target distribution as long as the source distribution is in the same account or if the source distribution in another account is disabled. To move a CNAME between accounts where the source distribution is still enabled, you must contact AWS Support and follow these steps.
