Not many. From my notes...might help someone out there. Going from non-bro-pkg to bro-pkg was the bulk of the excitement. Also if you've ran bro-pkg with sudo instead of just as root you'll have to tweak out the config file. Try as I might to bro-pkg upgrade ja3 it did not fly, but an uninstall and reinstall worked. The list of packages are ones I use, betting folks use things other than my tiny list. Thank you.

#@load packages/intel-seen-more/seen <- these
