Another MAC AccountEdge Pro qu

ok, this is turning into an absolute nightmare

Just spend the last hour with the so-call support team which had no idea how to solve my problem and they keep hanging up on me for some reason.

can someone here please help:  Let's put in this in plain English step by step

1) I am using MAC AccountEdge Pro v18.7 that I was told I have to stop using

2) I bought a new PC laptop just for MYOB

3) I bought the AccountRight Premier subscription

4) I have 2 company files I need to migrate to AccountRight

5) I got an automated email from "migration team" but the email says "if you want to migrate mutilple company files, you will need to have a separate serial number for each of them, and create a separate migration ticket for each company file"

my simple question, I only have ONE serial number for AccountRight Premier subscription (which caters for 2 company files).   

Do I gernerate two migration request tickets using the SAME serial number??

This is the question I have been trying to get for the past hour on the phone and I was literally in tears when they repeatedly asked me to read out the whole automated email from MYOB.  and the MYOB "support guy" kept telling me it should be fine just sending 2 files in that link?!  

but email clearly told me to rename the file to INC####.zip as they don't do the conversion if it's named different.  So how do I name my 2 company files the same name?!!  

So anyone can answer my simple question before I send over my files?

Do I gernerate two migration request tickets using the SAME AccountRight Premier serial number??

time for a coffee...seriously.... excellent staff training.
