[Not recommended because linking breaks between OS releases] Use Migration Assistant to import previous programs/data. However conflicts with old and new system occure, I recommend always doing a fresh install and not importing user programs. That way you know what you are dealing with!

Permissions

In Linux there is root and all other users. In Mac the Admin is the root and just onother user depending on context.
sudo su to access a root shell from admin.
They practice of using sudo for every root command is ridiculous(you must be encouraging weak passwords!).

Do not run accounts in admin (as this is effectively root). If they get your password to an admin account they have full control of the box. Many software problems are caused by running an account as an admin, only use the power when you need it.
