To correct Depreciation, Asset should be capitalized prior year

Hi Experts,

I have an asset capitalized last January 2016 and now our customer is asking this to change the capitalization date to Oct 2013.

I already capitalized the assets and it already posted its 2 months depreciation.

How would I correct its depreciation and reflect the capitalization date as October 2013 knowing that the asset is already capitalized and I can no longer post transaction in a prior years.

Please need your help.

Thank you in advance.

Bryan
