We got a comment on an old customer portal article. The article was only for 10.0, but it says 10.x, which was to set it apart from the 9.x content (separate article). I think it would be useful to one or both of do two things:

1. Update the links to 10.0 with the new pantheon docs for 10.1 after examining it for any differences (which should be minor, I think).
2. Mark the old CP articles for 10.x as outdated and redirect users to the pantheon docs for this release in case they have old bookmarks or arrive via google or something.

I checked the splash page and it looks like 10.0 is the only version that needs fixing. 10.1 and up all have the correct pantheon links.
