How can I change the valuation method in the stock settings in the Mid of Fiscal Year

While I’m trying to change method " FIFO to moving average" its says.

“Can’t change valuation method, as there are transactions against some items which does not have it’s own valuation method”

please help.!

Any Solution to this ? Other than recreating a new instance with opening entries for stock * accounts ?
