Once you initiate the upgrade, it will walk you through each step of the process. You can always decide to cancel the upgrade by closing the upgrade screen.
The first step of the process will ask you to publish any unpublished changes you may currently have.
Publishing before proceeding with an upgrade will allow you to save your work in case you decide that you want to revert the changes applied by the upgrade. This step is optional but strongly recommended.
The second step of the process will check your current theme. Themes must be compatible with the new site upgrade in order for the process to continue. If you are already using a compatible theme then you can simply apply the upgrade. If you are using an incompatible theme then the prompt will ask you to select a compatible theme from a list of compatible themes we found in your account.
Once you select a new theme, you will have the option to preview what the upgrade will look like. This link will open a new window and allow you to see what may have changed. It is important that you:
Check your design and make sure that there are no styling issues
Check for scrolling tiles
Check for elements that may be added or missing
If you are happy with the upgrade you may close this preview window.
If the theme you have selected has style presets you may be asked to map those style presets. This allows you to decide how your style presets transfer to the newly selected theme and apply to the places where the previous style presets were used.
You will finally be shown a confirmation screen as the upgrade happens in the background. You may decide to click done or preview the site again.
If you are unhappy with the upgrade you may click revert changes at the top of the site editor. If you published your site before proceeding with the upgrade then only the upgrade will be reverted. If you did not publish the site then you may lose some of the work you have done.
