Widgets has disappeared after migration

So odd…
This website uses Genesis Simple Sidebars. Nine simple sidebars were created years ago. Each of the sidebars contains contains one widget which is the attorney’s personal cv.

Today I migrated the website from one web host to another and suddenly every one of the widgets inside the 9 different sidebars has disappeared. They’re not in Inactive widgets; they’re just gone.

Is the widget content kept in a database table? Any thoughts on how to recover it?
Many thanks –
