Import website from previous version and change theme

[nikiinfo]

Hi everybody, I need to renew my website and I would like to import it in new 10 version and change the theme automatically, is it possible?
Then I would like add a new paypal button but the widget tool seems disappeared, how can I do (I try with import from web site contenent but it doesn't work: Unable to find the HTML code for the widget on the widget site or on the clipboard.

Configure your add to cart button in this PayPal window, following the instructions given.) is there a way to edit the pre-existing botton in the template replacing standard code with my own paypal button code?
Thank you so much, Niki

To the best of my knowledge you cannot change a theme from one to another.

But you can use one of the new templates and then copy and paste and drag and drop your existing content into the new template.

You can find the PayPal widgets in the new Content Gallery (Insert > From Content Gallery > Page Elements and Widgets) or in the Designs Gallery.
