Moving Blogposts?

Hi guys,

I’m redoing a site originally built on Enfold, with a new version, still on Enfold. To do that I set up a subdomain where I’m developing the new site and when this is ready I will move it onto the actual domain so the old site is replaced with the new one.

I would like to keep all the blogposts of the old site and put them (copy/paste?) into the new blog, possibly moving all comments as well, so I don’t lose track of what I built over time.

How can I do that?

Thank you,

Antonio
