I currently have two Joomla 2.5 websites. Let's say site A and site B.
Currently, sites A and B share user, group, and session tables (one is a mysql "view" of the other). A holds the real table.
I want to upgrade site B to Joomla 3.x but it seem like the password algorithm has changed. So, upgrading site B will mess up all the user passwords on site A.
Is there any good way to sync users so that they can log into both sites using the same password? And if they sign up on one, they are also signed up on the other.
