According to Wayne Luke:
So does this mean that any links to my site that are posted on another site, could be directed to the wrong thread as the thread ID number changed?
Why are my forums, threads, blogs, social groups, etc... renumbered? Or why does everything have new IDS?
Due to the new database structure of vBulletin 5 along with Channels and Nodes, the upgrade is actually doing a lot of importing from old tables into new tables. Since sites usually delete content, forums and so forth, there are usually gaps in the IDs of these items. During an Import these gaps are eliminated due to how MySQL and auto-numbering work.
