'Upgrade to Drupal 8' guide needs a page for a situation where site builder needs to make custom migrations. Topics to include at least:

- mapping of fields when site builder wants to map to a new field which didn't exist in source

- custom process plugins

- hook implememtation / subscribing to events

Note: remember to link to this new page from the 'Known issues' / plain text formatting section.

Another fine example of your writing, masipila. One question, is this the page to mention hook_migration_plugins_alter or not?

Thanks for taking the time to review this quietone!

hook_migration_plugins_alter definitely belongs here. I wasn't aware of that earlier. I'll add an example of how this can be used.

Cheers,
Markus

Thanks for adding the hook alter. I think that is sufficient to let people know about the hook and to get them started.
All done here!
