We will see the migration banner when CC is about to be updated.

So far, Community Central and Fandom Devs Wiki are the only wikis that still do not have the migration banner, at least to my knowledge. Though this may not be correct, to my knowledge this wiki and Fandom Devs Wiki are the last wikis still on Legacy as of right now.
