We tried on our other beta site, but when importing the demo or the version you want, it deletes all the existing pages and replaces them with new ones. Therefore, we cannot take advantage of any version added by you. We have our tired pages to translate into our language, as well as other pages. We want to import the new version so we can take time to replace your logo and change the content before it appears live to customers and we need to keep some of the existing pages. I think if there is no choice, it is better to go to buy another theme, because we are 4 years on this theme without a technical solution to benefit from any new release. Please let us know if there is a way.
