1401252 - Squash kuma migrations

Status: RESOLVED FIXED

(developer.mozilla.org Graveyard :: Code Cleanup, enhancement)

Description

[John Whitlock [:jwhitlock]]

Django has a process for "squashing" migrations, to combine a sequence of migrations into a single migration:

https://docs.djangoproject.com/en/1.8/topics/migrations/

It will be useful to do this before the 1.9 - 1.11 update, to reduce the number of historical migrations that need to be updated due to API changes.

Historical data migrations, that have already been applied, can be removed from the squashed migrations. This will speed up testing that runs the migrations. It can also remove the data migrations that add the utf8_distinct_ci collation [1] and then remove it [2].  This will allow us to use standard MySQL installations in our testing infrastructure.
