MY new myob bms id number not transferring correctly

I am in a world of pain at the moment and require MYOB specialist help.

I had only used MYOB Payroll Essentials for one client only for STP. However, due to MYOB cancelling offline files, I bought a subscription so I could upgrade my offline file to online. This offline file is where I processed a full accounts service, including payroll recording, but not STP reporting.  THe STP Reporting was done at the end of the month and was only reported through Payroll Essentials.

After upgrading the original offline file to online, it now shows 2 STP Reprts for the same employer. All the employee records are duplicated, showing everyone earning double what they actually did.

Even though the MYOB Payroll person took about 4 hours to walk me through everything, it still did not work. After going through BAS agent portal, it shows two separate bms id numbers and did not merge the old number with the new online database.

Now I have been told to "zero" everything out of my Payroll Essentials. Surely, there must be a way to transfer the old Bms Id to the new file.
