2.5 to 3.0 upgrade fails with elasticsearch error

We are attempting to upgrade from 2.5 to 3.0 using ubuntu package files. Graylog is failing to start with the following messages in syslog:
Jun 19 17:35:42 ip-10-0-10-54 graylog-server[19369]: Exception in thread “main” java.lang.NoClassDefFoundError: org/elasticsearch/search/aggregations/ValuesSourceAggregationBuilder

Jun 19 17:35:42 ip-10-0-10-54 graylog-server[19369]: Caused by: java.lang.ClassNotFoundException: org.elasticsearch.search.aggregations.ValuesSourceAggregationBuilder

Versions as follows:
graylog: 3.0.2
elasticsearch: 5.6.16
MongoDB: 3.6.9

The issue was some 2.4 plugins left over from previous installations. I moved them and things are now working.
