The theme update process will differ by the methods you chose to install your theme. Please choose the methods listed below to see the details.
Before updating your theme
Please be aware that all your installed third-party apps, code modifications, ‘.js’ and ‘.css’ files will be valid for the theme you have made those modifications on. When you update your purchased theme, the updated theme will be available as a different entity than the old version of itself. This means when you switch to the updated theme, these modifications will not be apply for this newly updated theme and you will have to make the same modifications again.
