I often see this issue in GPF-Blogger:How do I?. Transferring Blogspot Blogs from one mail ID to another. Note: The Old UI is gone long ago and we have only New UI. Make sure that both Mail accounts are associated with https://www.blogger.com/ Use Mozilla browser(say). Login to blogger account from which the blogspot blogs should be transferred. Go to :- Settings => Permissions => Add Authors => Give the m@il Id of the account to which the blogspot blog should be transferred => Invite [ Old UI ] Settings => Basic( if necessary ) => +Add Authors => Give the m@il Id of the account to which the blogspot blog should be transferred => Invite authors [ New UI ] Now, use another browser (say Chrome ) and login to the mail of the blogger account whom you invited in the previous step and accept the author invitation. This is the account to which the blogspot blog should be transferred.
