hey!

vbulletin stores the posts in the database and uses a cache (table: postparsed). To clear the cached old/new urls you have truncate this table.

this means... no cached postes will only be overwritten in the postparsed table. the original post is not overwritten (table: post).

after installing only new posts will be overwritten, but you can truncate the postparsed table as explained.

i hope this helps.
