By default CMS2CMS service migrates content featured / intro / cover images from Joomla, WordPress and WiX, for example:

WordPress featured image

WordPress featured image

WiX cover image

Note: If the featured image was not set on your existing website, the first image in the content body will be migrated as a featured one only with “Set first image as featured” option.
