One way to move a post from one blog to another is by copying and pasting it into the post-editor in a new Post in the second blog.
However sometimes this doesn't work: formatting, picture positions or hyperlinks are lost.
But behind every Blogger post is just HTML: and, you can can copy content from one Post to another by copying the HTML, and pasting it to the destination blog as HTML.
This works even if the blogs belong to different Google accounts (although sometimes you may need to save the HTML in a text-editor (notePad) while you log out and in again, or perhaps even email it (as a plain-text) message to someone else who has author rights in the second blog.
You can follow these steps to move a post to another blog
1 Log in to Blogger, and Edit the post you want to move.
2 Click on HTML to see the code behind the post.
3 Copy all the code
(put the cursor in the code, ad press Ctrl / A to select it, then press Ctrl C to copy)
4 Open the blog that you want to move the post to
(You may need to log out and in again, or perhaps just switch to different browser or tab)
5 Create a New Post
6 Click on HTML, so you can see the space where the code goes
7 Paste all the code
8 If necessary, click on Post Options and make any changes you need there
(eg viewing or not viewing comments or back-links)
9 Click Publish, and check that it looks ok
This an easy way to move an individual post / or part of a post
there are other easier ways to move all posts between blogs, and move some posts between blogs. (heruqua)
