A. This act¹ does not affect an action or proceeding commenced before this act takes effect.

B. If a security interest in a security is perfected before this act takes effect, and the action by which the security interest was perfected would suffice to perfect a security interest under this act, no further action is required to continue perfection. If a security interest in a security is perfected before this act takes effect but the action by which the security interest was perfected would not suffice to perfect a security interest under this act, the security interest remains perfected for a period of four months after the effective date and continues perfected thereafter if appropriate action to perfect under this act is taken within that period. If a security interest is perfected before this act takes effect and the security interest can be perfected by filing under this act, a financing statement signed by the secured party instead of the debtor may be filed within that period to continue perfection or thereafter to perfect.
