Are @*.comcastbiz.net email addresses going away with the Office 365 migration?

Do any Comcast reps monitoring this forum know if @*.comcastbiz.net email addresses are going away eventually with the Office 365 migration or are those separate and being left alone?  Our scanner uses an @comcastbiz.net email address for scan-to-email so I would like to know if I need to make alternate plans for that function?

Thanks.
