We are in the process of implementing changes to the blog look and feel for our client. We did migrate some of the data to the blog. Once we are done with our customization, we would like clear all data (except users) and re migrate data. Is there a way to bulk delete blog, media, comments, tags, categories, etc except users.

Last time when we did migration, we used the import tool and we had a issues migrating blogs but particularly media. We got help form your support staff but it took a month to get the migration right. We would like to know if we can get support this time around. We actually had to send the export file from Movable type ( blog software we are importing from) and then your support was able to get blog and then media loaded after a lot of back and forth. We would like to avoid it this time around and would like to know what process should we follow.

Thanks.
