The repeal of any statutory provisions by the Mississippi Code of 1972 shall not affect any act done, or any cause of action, or any right accruing or accrued or established, or any suit or proceeding had or commenced in any civil case, or any plea or defense or bar thereto, previous to the time when such repeal shall take place; but the proceedings in every such case shall be conformed, as far as practicable, to the provisions of the Mississippi Code of 1972.
