Comment (by azaozz):

 This mainly concerns:
 - `post_content` (image description).
 - `post_excerpt` (image caption as saved in the DB).
 - `_wp_attachment_image_alt` (alt text for the img tag as saved in the
 DB).

 Seems it may make sense to migrate the description and caption. Editing an
 already used image may require new description, and migrating the old
 description may be somewhat unexpected in these cases. On the other hand
 it is still the same image...

 Unsure about migrating the alt text though. According to
 [https://www.w3.org/WAI/tutorials/images/decision-tree/ W3C WAI] the img
 alt must be contextial. Even storing it in the DB is "questionable" when
 inserting an already used image, see #47456.
