Thanks for your post.
Yes you can export and import the templates from your old QuickBooks files to new one by simply following below steps:
1. Open your old QuickBooks file then go to List -> Templates and then right click on the template which you want to export and then click on Export and then you can save that to your computer.
2. Then open the new QuickBooks file - go to List -> Templates and then click on Templates option (at the bottom of the page) and then click on Import and then select the template you would like to import
Please let me know the outcome.
Hope this helps.
