I recently re-started blogging after disbanding my old website several years ago. Whilst travelling around China it made sense to record my experiences in a WordPress.com blog. After coming home i didn’t feel that i really had much to talk about anymore and eventually took the site down.
I managed to drop all of that old content into this new blog through a combination of WordPress importer plugin (RSS) and using Archive.org to find other old posts that were not in the various export files that i managed to dig off my old harddrive. This combination worked well as there were only about 80 posts or so to move across and most images were links to my Flickr account, so were still working fine.
One issue that i did run into was that after trying out several different import plugins, my admin area started to run incredibly slowly and so i would advise anyone to de-activate and delete these plugins as soon as they have completed their content migration.
