New to Forti, any good video series?

Hey All,

After the last round of insane pricing from Palo, we've decided to slowly start moving over to Fortigate's for our firewalls. Any good series/tutorials we should know about? We've got a crew of good network engineers but no real experience with forti specifically, just trying to find the gotchas or anything we should watch out for. We're running a self hosted Fortimanager, and have a bunch of 71G's to play with.

Thanks!
