Anyway, I was running vbseo (a mistake it turns out imo)
My urls were like this:
so url/node(as you guys call it)/thread id - title.html
If that makes sense?
to be honest, I wasn't that bothered about losing all the indexing in google, as I knew it would reindex in time. What this blinded me to was the fact that my internal linking would fall over ...
So, I have decided well after upgrading that I would now like to set up redirects on my old thread urls ... Is this possible?
I have searched a bit on the forums, but its a little like tumbling down a rabbit hole when you don't know what you are looking at ... and regex is a mystery at best to me!
