I have a website with 14K registered users. There is new section of that website which has been developed as a separate Drupal installation. The users in the old website should be able to login with their username and password to the new site.
My questions are :
is there a way to connect new site "user registration/login/forget password" features with the old one?
Should i sync the databases all the time? Or when the new user registers, his information is added in to new and old site ( and Vice Versa)
What is the best practice in such cases.
thanks :)
