Welcome to the Community page,
So it is not possible to do this. This cant be done, you cant move from a UK version to a US version. You can only move from a UK to UK version.
You can utilize a migration tool as a workaround.
Another option, consider purchasing a 3rd party conversion service, not 3rd party conversion program. Our team developed our own conversion program but some procedures still have to be run manually. Contact us in private for details.
If you decide to use QBD US version, You may consider purchasing QB Desktop 2021 or 2022 Accountant edition for 10 users with the one-time license. You will install the license on 10 machines but you are only allowed up to 5 users working on the same file at the same time.
