The board of trustees shall take such actions as it deems necessary or appropriate to provide for the joint administration of the retirement system and the Teachers' Retirement System of Louisiana and the Louisiana State School Lunch Employees' Retirement System; however, no action shall be taken which would impair the integrity of the board of trustees of each of the systems or the integrity of the funds and investments of each of the systems. The boards may, pursuant to the authority herein, appoint the same secretary-treasurer or secretary-manager, any other provision of law to the contrary notwithstanding. Funds appropriated for the administration of each system shall be used for such purpose and in the category of expenditures appropriated but otherwise may be transferred to accomplish the purposes of this Section.
