Online Advanced Restore or Copy results in incomplete and inaccurate data

Intuit advertises how simple and easy it is to do Backup, Restore, and Copy in Online Advanced. Unfortunately none of it works. A backup is worthless off the restore/copy doesn't work,

For months I've been attempting to copy from one online advanced company file to another. I followed all the online instructions (which are incorrect). The Backup of company A have all shown as successful, automatic or manual. At first, the Copy to company B would take a crazy long time and eventually fail. After 4 cases opened on that issue and two investigations, the Copy process now completes and reports success. I thought I was home free.

When I do the first basic data verification, a Trial Balance, it is clear that something went wrong in the Copy process. Some of the numbers match and many do not. Yes I'm comparing reports of the same date and accounting method. There are accounts which show active and with a balance in company B which in company A have a zero balance and are inactive. Other accounts the balance is just off.

Intuit indicates there is an open investigation into this issue. INV-145834. That investigation has been open for 3 months with no apparent progress. It seems this is a low priority. It's unclear to me how wrong numbers in an accounting program can be low priority.

Has anyone out there had any success using restore or copy and gotten correct data in the resulting trial balance?
