Not perfect for huge sites, but five stars support!

The plugin has one downside: importing a huge site can be tricky. I migrated a 4000+ posts, 1000+ keywords site from one (old) host to another, and imports tended to end before completion. You can restart an import where it was, but sometimes some database recordings are missed (my guess is the one the connection broke on can be lost sometimes).

So as a workaround, I made a local MySQL backup of my Spip database, created a local WordPress site, used the plugin locally, and then exported the local WordPress site to my final host. That way, 1- the process is quicker so the risk of failure is lower 2- I could more easily check if everything had transferred, as everything was on the same database one the same computer.

I also discovered a few bugs in the process (I think we had every type of taxonomy and links Spip was able to generate, with editors mixing complete URLs, local URLs and Spip shortlinks to posts, keywords and categories, all that often in the same post with random spaces before/after the post IDs!).

And here’s the important thing: not only most of it worked out of the box (using the Pro version to manage taxonomies), but the plugin editor was one of the most reactive I’ve ever seen. Any bug report was usually assigned in the hour an corrected by the next day.

So an overall efficient plugin (with some caveats for huge databases on slow hosts), and a very efficient support if you have any problem on the way.
