We are re-developing a site using zend framework, which uses SHA1 password encryption. The old site used OLD_PASSWORD() encryption. Now what's the best way to migrate the user data? Is there any hack for decrypting the OLD_PASSWORD as I guess, if we have to use the same encryption, then we have to develop the auth/login outside zend and it will take more development time.

any suggestion?

Looks like HERE is the implementation of OLD_PASSWORD(). SHA1 hasshing is one-way hash, you cannot revert the hashed string to it's clear version. What you could do is use the OLD_PASSWORD implementation and then use SHA1 hashing to compare it with the stored value in the database.
