Anyone else having problem with a 6.3.0 search head cluster talking to a 6.2.3 indexer cluster?

[wlth09]

The moment I upgraded I started getting:

The searchhead is unable to update the peer information. Error = 'failed method=POST path=/services/cluster/master/generation/..../?output_mode=json master=...:8089 rv=0 actual_response_code=400 expected_response_code=200 status_line=Bad Request error=No error' for master=https://...:8089

The cluster master is giving the following:

09-29-2015 19:33:23.050 +0000 ERROR AdminManager - Argument "host" is not supported by this handler.

Anyone else seeing this?

The pper nodes and search heads must run on the same or lower version than the master node of the index cluster
