Re-use of database with PHPass passwords

Question

Just need a little advice. I have a website based on CodeIgniter and using TankAuth and PHPass. I want to recode the website with another framework (Symfony 2).

Is there any way to allow user to log with their existing password or do I absolutely need to ask them to set a password again ?

Thank you very much :)

Answer 1

The best is to reset all the password and warn users through email or ask them to change the password with the new system.
