We have a Sitecore site that currently exists in production with a lot of content, on the order of half a million article items and supporting content around those articles. We have to relocate those items to another area in the tree (for business reasons that aren't relevant to the question). The structure of the items will remain the same, we just need to move them to a different area. The
<site> node start paths will be updated to reflect the new path, so no urls will change.
I have to get this done as quickly as possible to minimize content authoring downtime. We also need to publish this change, and a full publish takes hours. What's the fastest way to accomplish this?
