Mass additions

Hi Guru's,

                I have an Issue in prepare Mass Additions where there many Assets unposted in FA with Status of "New". All these Assets are old since they have not been posted since 2008 year.

             So my doubt is, If all those Un-posted assets are posted in current date, will the depreciation be calculated from the begining date of the Asset since when it is transferred from AP  or will there be any Issues if all those bulk Assets are posted all of a sudden in a current date. Please advise what to do with these Unposted assets with Status=New in Prepare Mass additions.
