msdeploy -verb:migrate source:archivedir=C:\dir,encryptPassword=pass -dest:webserver60 -replace:objectName=metaProperty,scopeAttributeName=name,scopeAttributeValue="ServerBindings",match=sourceIP,replace=newdestinationIP
where match is a regular expression string to match the binding values in the source. You can read more about replace here
