Attempting to move QB 2017 from a Win7 machine to new Win11.

We followed the instructions for the migrator and successfully have the data on a flash drive.

We inserted the flash drive in the new Win11 machine. Executing the flash drive migrator.exe file opens a window requesting the temporary password which we supplied and was accepted.

However, the next window to persistently fails with the unhelpful comment: 'Something went wrong, Try again later;'

QUESTION 1: Is the process failing due to QB being 2017 and Intuit wants a current version?

QUESTION 2: We started to try the manual process but we need to clarity something first. The 'find account' page says it works across Intuit's programs. But, If we have data files for two different instances of QB for two different companies we're concerned that having the same account number might mix up and automatically (in some way) the data files and not keep them separate as they are now?
