If it’s an update that can be managed via a SQL update query, then I think it could be done. If it’s something that has to be done manually, then clearly it’s a no-go.
One thing about the 10,000 hits though… one of the issues with the software used for BOB is there are multiple URLs for the same “page” in many cases. I can reference a post within a topic, a page within a topic, or the topic itself. There is also the regular version and the print version. So the actual number of posts that include SAP wiki links is probably far fewer. (Side note: This is actually a problem for Google that has been addressed in newer versions of the software to some extent.)
If I get a chance I will run a count and see if I can get the real number.
