I have a blog I've been hosting at Tumblr for a number of years, using a custom domain name.  Let's call this example.com.  I'm planning a migration off Tumblr to a server I control.The problem I'm facing is -- even after I point example.com to my own server (where I'll have a separate blog system running), the content will still exist at Tumblr -- just at the default tumblr domain namehttps://my-tumblr-username.tumblr.comIn addition to this, Tumblr inserts a canonical <link/> tag into the <head/><link rel=canonical href=http://my-tumblr-username.tumblr.com/post/545364745/post-title />Is there a way to control this tag in Tumblr?  I'd like my domain to be the canonical source, but I didn't see an obvious way to tell Tumblr to remove this link, or to have them point to my canonical domain name.  It doesn't appear to be part of the Tumblr design template.Is my only option to delete the posts from my old Tumblr site completely?
