Going around in circles and dealing with the migration issue isn't easy, @AM3P. I recognize the impact of this situation on your finances and time, and I'm here to share a fix so you can complete the transition.

One significant factor that can affect the time it takes to complete the migration is the size of your company file. If your file is relatively large, it can take longer for the migration to finish successfully. As a general guideline, the total data targets within your file should ideally be below 1.2M for a smoother transition to QuickBooks Online (QBO).

Given that this has taken up a lot of your time, you can stop the migration and consider condensing your data to reduce the file size. When you condense your company file, this action cannot be undone, so ensure to create a backup copy before you do it.

1. Navigate to the File menu, then Utilities.
2. Select Condense Data.
3. Select Keep all transactions, but remove audit trail info to date, or Remove the transactions you select from your company file.
4. Select Next.
   
5. Follow the onscreen process then wait for the process to complete. Select Close.

Once done, you can then proceed to move your QBDT file to QBO.

If the migration process remains stuck even after reducing the file size, I recommend following up with our Support team regarding your situation. They have the expertise and tools to provide additional insights or address any underlying issues causing the delay.

Additionally, please be aware that some data does not transfer when converting your QBDT files to QBO. You'll want to learn the complete lists of features and data that move from the desktop to the online version. It includes details of how your books will convert when switching to a different QuickBooks version.

Your input is valuable, and we want to ensure you'll have further assistance with us when migrating your file to QBO. Let us know in the comments below. Stay safe.
