We have a SharePoint 2013 Site Collection with approximately 200 subsites that allow inherit several content types from the parent. Since we're flattening the hierarchy during the migration to SharePoint Online, we'd like to move the content types to live in the central 'content services' content type area. Does anyone know if this possible to do during a migration or will we need to rebuild those content types and then map the subsites to the new location?
Thank you in advance for any guidance.
