Fixed Assets Cost clearing accounts Balances

Hello,

I just want to ask what is the recommendation solution to clear all the balances for the fixed assets cost clearing in all entered currencies , i mean these balances are accumulated balances for more than one reasons like manual assets addition, an old cases from more than 5 years which opened the cost clearing in AP and not closed in FA , any recommendation to clear all balances since we are sure that there is no outstanding balances need to move to the FA
