Datastax opscenter upgrade fails to display stats

I upgraded Opscenter from 5.1.2 to 5.2.0 yesterday, and now none of the graphs on the Dashboard are showing any statistics.

My cluster is datastax enterprise 4.5.1 with the following versions:

cqlsh 4.1.1 | Cassandra 2.0.8.39 | CQL spec 3.1.1 | Thrift protocol 19.39.0

I'm using this cluster for a search workload with solr. The agent.log is filled with the following:

INFO [qtp1313948736-24] 2015-08-06 12:30:52,211 New JMX connection (127.0.0.1:7199) INFO [qtp1313948736-24] 2015-08-06 12:30:52,214 New JMX connection (127.0.0.1:7199) INFO [qtp1313948736-24] 2015-08-06 12:30:52,218 HTTP: :get /cluster/solr-cores {} - 200 INFO [jmx-metrics-1] 2015-08-06 12:30:57,186 New JMX connection (127.0.0.1:7199) INFO [jmx-metrics-1] 2015-08-06 12:30:57,191 New JMX connection (127.0.0.1:7199) ERROR [cassandra-processor-4] 2015-08-06 12:31:15,082 Error when proccessing cassandra callcom.datastax.driver.core.exceptions.InvalidQueryException: Unknown identifier timestamp

Any ideas?

The migration on upgrade failed. Can look through schema with describe keyspace "OpsCenter" and find tables not upgraded to 5.2.0 (look at comment). The changes made are here:

-- depending on how far through the migration you progressed, parts of this may fail
-- this assumes you're using the default name of "OpsCenter" for the opscenter keyspace, otherwise 
-- you'll have to rename the "OpsCenter" part.
