Can it possible to copy Existing organisation information( Average costing) to newly created organiz

 Hi ,
Scenario,

 in our organization we have been using inventory organisation with Average costing method. But recently due to management decision we are planning to change same organisation to FIFO method.

So i knew , if the organization is defined with one particular costing method ,it wont accept to make any changes regarding costing method.

 So my Question is can it possible to create another organization with FIFO costing method and copy all the existing organization(Average-costing) information into the newly one.

Please provide the solution its very urgent for our organization as well as me .

Thanks a lot!

Satya.
