Rebuilding summoners

[Cerwin]

I know that I read somewhere that all summoners had to be rebuilt as unchained to be PFS legal. Unfortunately I cannot for the life of me remember where I read that. It came up in my game last night. I let the guy play his regular summoner because I couldn't remember where it said that and he was under the impression that his summoner was grandfathered in. Can anyone please help me find where it says that the only PFS legal summoners are unchanged? Or and it is possible that I'm wrong in which case can someone show me where it says that old summoners are grandfathered.

Blog post - Grandfathering happened for any summoner that was played with 3 XP or more at some point before the blog post became live.

It's in the Additional Resources document in the Advanced Players Guide section, which is where you would normally look to see whether APG Summoners are legal:

As of 4/27/15 the summoner class in this book is no longer legal for play. A summoner character that has played at least once at level 2 or higher by this date qualfies to continue using this version of the class. Otherwise, only the summoner in Pathfinder RPG Pathfinder Unchained is legal for play.

Ok thanks I guess I was wrong. It happens every once in awhile.
