My mistake deleted customer mater while uploading

Dear all,

By mistake while uploading few customer record i have deleted all the records, so tried my best to get back the lost record how ever i found  that  i have a copy of same custtable in test company   , so my whole idea was to copy the whole custtable from test company to live enviroment  but it is not working tried other steps....

ran this job also :

CustTable Custtable1,custtable2;

changecompany("TEST")
{
    while select Custtable1
    {
        changecompany("live_company ")
        {
            custtable2 = null;
            buf2buf(custtable2, Custtable1);

            if (!custtable2.validateWrite())
            {
                throw Exception::Error;
            }
           
            custtable2.insert();
            ttscommit;
        }
    }
}
