New Guide: WordPress to WordPress, incl. updating data to a new schema

[carstingaxion]

I’d like to suggest a new Guide to help people doing a Relaunch of an existing site.

I believe that relaunching a site is one of the greater challenges and that’s why I would love to see some well-written best-practices to help with that.

Simple use-case: You need to swap plugins, that provide you with a subtitle field (or block). This is usually saved as post_meta, but the meta_keys used by the old and the new plugin differ. So you need to change that.

More advanced use-case: You need to separate all posts from the Books-category into a custom post type book, while keeping all existing taxonomy-relations of the former posts.

WordPress provides several options to hook into export, as well as into the import, I could modify the wxr-file manually or use a kind of search-and-replace tool. And on top I have to decide if it is better to do all these things prior, during or after import.

This or similar topics should be covered within one or multiple guides, I think.
