Migrate to Elasticsearch 5.1.* when it's stable enough
-
Remove requirement for delete_by_query
plugin as it's already built-in -
Make sure search works as expected (changes to the mapping and some search queries are needed here) -
Make sure documents gets deleted when project is deleted (API to delete_by_query
functionality has been changed) -
Update rake gitlab:app:check
task -
Requirements -
Update the update guide -
Check if we really need to rebuild index. Maybe that's enough to migrate index with ES official migrator.
