(a)
This division determines priority of conflicting claims to collateral. However, if the relative priorities of the claims were established before July 1, 2001, former Division 9 (commencing with Section 9101) determines priority.
(b)
For purposes of subdivision (a) of Section 9322, the priority of a security interest that becomes enforceable under Section 9203 dates from July 1, 2001, if the security interest is perfected under this division by the filing of a financing statement before July 1, 2001, which would not have been effective to perfect the security interest under former Division 9 (commencing with Section 9101). This subdivision does not apply to conflicting security interests each of which is perfected by the filing of such a financing statement.
