This is really frustrating and I hope someone can help as QB support has been 0% on this this far.

We are in the process of purchasing a company that currently runs on Quickbooks Enterprise v23 i believe,

They want to keep their instance of QB. We have now tried multiple ways and failed in trying to import that data into our instance, We only want to export the last 5 years of data from Enterprise.

We have a new instance of Quickbooks Online Advanced and the current dataset is on Quickbooks Enterprise v23

Here is the list of data we want to import:

1. Customer Data

2. Customer Transactions

3. Items

4. Vendors

5. Vendor Transactions

Quickbooks Online CANNOT import any of the IFF files Enterprise exports.

Quickbooks online seems to have a complete different structure flor customer lists (our list is 25k users.

We have even tried to create a new business in the current Quickbooks enterprise and then tried to bring in the above files in IFF and after taking about 4 hours on a Customer Data file - it completes with about 5% success rate and 95% Errors. Without the option to even know what went wrong.

When contacting QB Support they say this is a Microsoft problem? Yip, their unwires for not being able to move data from their own product to another one of their products is someone else's problem. I am beyond lost for words on this. Both these products cost well over 2k a year.

I cant imagine that there is no ability to take data from one instance to another in QB.

All help would be really appreciated on this.
