One of the biggest things I noticed in 6.2 is my VPN events section disappeared in 6.2. I used to use this to rule out any phase1 issues, and the diag debug commands for everything else. In 6.2 it was no longer there.
In talking with my friend and colleague, Manny Fernandez, he said he stumbled upon this by going to Log & Report > Events, and there's a drop down in there showing where the logs are. See image below:
Big thanks to Manny for highlighting this. I hope this helps!
