"""Data migration for some legacy process attributes.
Attribute keys that are renamed:
* `_sealed` -> `sealed`
Attribute keys that are removed entirely:
* `_finished`
* `_failed`
* `_aborted`
* `_do_abort`
Finally, after these first migrations, any remaining process nodes that still do not have a sealed attribute, have
it set to `True`. Excluding the nodes that have a `process_state` attribute of one of the active states: `created`;
`running`; or `waiting`, because those are valid active processes that are not yet sealed.
