I am wondering if SMF may import users' password in vBulletin without reseting them? I don't want all my members to require their new passwords and reset them. Thanks.

Their passwords should remain the same after the conversion.

that sounds wonderful. you use same encryption on password as same as vBulletin?

No, but vBulletin just uses md5 (if I remember correctly) and that will be automatically upgraded to SMF's encryption as people log in.
