So some stuff worked and some didn't. A quick check of the D8 site shows content types but no content, and a bunch of errors in the log:


filter 26 Jun 2015 - 09:10 Missing filter plugin: filter_null. Anonymous (not verified)
filter 26 Jun 2015 - 09:10 Missing filter plugin: filter_null. Anonymous (not verified)
filter 26 Jun 2015 - 09:10 Missing filter plugin: filter_null. Anonymous (not verified)
...


I suspect one of these occurred for each piece of content which prevented the import of content from completing.

All the files imported, and I suspect I need to investigate each of the errors in turn, these look like the important ones:

A good way to remove these errors seems to be updating all the current D6 modules to the latest versions (thanks 'drush up'!). Disabling and removing some of the unnecessary migrations (like aggregation) seems like a good idea too.
