Thanks for getting back to this thread, @Buck Tsai.

It would be best to contact Sage Pastel Partner support for further details about this matter. This is to ensure that there is migration assistance between Sage Pastel Partner and QuickBooks. 

Let's also check for any possible suspicious emails. This can sometimes be a scheme to get you to share your personal info. 

Here are a few things to look for if you’re not sure an email came from Intuit:

• We’ll never ask for your personal info in an email.
• Our emails will always come from an email address that ends with @intuit.com. This includes @e.intuit.com.
• Any link we send you in an email will always be for an intuit.com address.

You can go to our Online Security Centre page to see how we protect your data and how you can protect yourself from email scams and other security risks. To see a list of suspicious emails and actions, or to report one of your own, select Go to security.

For more information, please see this article: Identify suspicious activity, phishing scams, and potential fraud.

Feel free to get back in here if you have further concerns with migrating data from Sage Pastel Partner to QuickBooks. I'm always around to help. Keep safe!
