I'm just about to roll out a new Pathauto Alias to include a new taxonomy term, which will modify about 1000 nodes. Is there a way to preserve the current path aliases I have now, and then bulk update all my nodes to the new pattern? I assume I'll need to use Path Redirect in conjunction with Global Redirect to keep the old paths pointing to the new paths?

Apologies if this has been asked before, it seems like a very obvious question, I just don't seem to be searching for the right terms :(
