WordPress makes importing blogs simple. Now, this may not be specific to MU, in fact it isn’t. But after burying myself in database dumps far too deep for for my liking while migrating Jerry’s original blog to this new Tripawds Blogs community, I was prepared for the worst when users asked about importing existing Blogger blogs to Tripawds.
I knew importing posts and comments would be no problem. But I assumed all images would need to be downloaded and provided to us so we could upload them to the user account account here. Then, I figured I would need export database tables for the new imported blog and search/replace image URLs to point to the proper /blogs.dir/files/ directory. After all, that’s how I had to make images display after finding this helpful post about to migrating from WordPress to WordPress MU.
But you can forget all that. After playing around in my new sandbox, I discovered that image URLs from Blogger posts are absolute and migrate absolutely. I created a test blog on Blogger, then ran the import from my Tripawds blog, and voila! Images displayed just fine. As long as the Blogger (or other blog platform) account remains active, with the hosted image files in place, everything should be just fine. And better yet … no upload space quota is used by those images hosted at Blogger.
The only drawback I noticed was that post labels get imported as categories, instead of tags. But then I bet the WordPress Categories and Tags Converter tool does just that, just as well. It’s amazing what you can learn by actually doing something.
