Okla. Stat. tit. 12A, § 12A-8-603: Savings clause

A. This act 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.
