Good evening, @comoltd. 

Welcome back to the Community! 

Use the Punch Time Export or Manual Time Export to download historic time data from one QuickBooks Time account and upload it into another using a CSV. 

Note: If you don’t have the CSV export available in your QuickBooks Time Reports, please reach out to support to get it added.  

1. Log in to your admin account in QuickBooks Time.
2. Select Reports and then either Punch Time Export or Manual Time Export.

• If you have more than 1 report, it'll be under Custom in the Reports section.

       3. Choose the filters you want.

       4. Tap Download Report.

Review this guide for some additional details: Export or import data in QuickBooks Time. 

I'm only a post away if you need me. Have a great day!
