I'm looking to do a custom import from a custom cms to wordpress. Looking at the export/import files in wordpress, I can get match most of the structure. Though, it is missing the relationships for custom taxonomies and posts when exporting/importing.
Is there a fix for this or would it be easier to not use wordpress's import script? Rather, write custom SQL to handle it all.
Also, as I am developing this new site the content in the old site (custom cms) is still being updated. There will be a freeze a few days before launch, where I can do another db dump and reimport. Though, the issue I'm foreseeing is that I will need to delete all posts and relationships and reimport the content. Is there an easy way to delete all posts and relationships to prevent any duplicates and reimport the content?
