I should also say perhaps – the page I would like the users to edit is a custom post type created with the types plugin. It has various child post-types and repeating fields, so I very much doubt that plugins for inline editing would work.
In my case, the URL’s aren’t easily translated. This post seems to have a pretty accurate description of how Blogger generats urls. Blogger seems to omits the words ‘a’, ‘an’, ‘the’ & limits the slug length.
I do not know if this is consistent across all blogger blogs, the one I am migrating uses a personal domain name.
The blog I am migrating has almost 300 posts, so I’d rather not do this by hand. I thought I saw somewhere that it should change the URLs if pretty urls are enabled, but this does not seem to be the case for me.
