Index and forward, intermediate Splunk Indexer not forwarding data

[somesoni2]

I am trying to implement a multiindexer environment where my two indexers are on different version of Splunk. IDX1 is Splunk 5.0.1 and IDX2 is 6.0. IDX is current working Indexer. It has data from all the forwarders.

What I am trying to setup IDX1 to index as well as forward all incoming data to IDX2. I have configured IDX2 to receive on port 9998, IDX1 is configured to send data to IDX 2. Below is the outputs.conf on IDX1.

[tcpout]
defaultGroup = IDX2
indexAndForward = true

[tcpout:IDX2]
compressed = true
server = <IDX2 Host>:9998
sslCertPath = XXXX.pem
sslPassword = $1$7kxWZaCKikBUbg==
sslRootCAPath = CAXXX.pem
sslVerifyServerCert = true
useACK = true

I restarted both the servers after configuration, but the IDX1 is neither indexing nor forwarding data.
Error message on _internal index on IDX1

11-15-2013 13:14:55.453 -0500 INFO TcpOutputProc - Connected to idx=X.X.X.X:9998 

Is there any configuration I am missing? Appreciate your help.

Resolved. With following configuration.Splunk 6.0 Indexer
Inputs.conf

[SSL]
password = certpassword
rootCA = $SPLUNK_HOME/etc/auth/blah_CA05_root.pem
serverCert = $SPLUNK_HOME/etc/auth/sslKeysfileDEV.pem
requireClientCert = false

[splunktcp-ssl:9998]
compressed = true

Splunk 5.0 Indexer
outputs.conf

[tcpout]
defaultGroup = DEV_INDEXERS_6_0
indexAndForward = true
disabled = false

[tcpout:DEV_INDEXERS_6_0]
compressed = true
server = <splunk6 indexer server>:9998
sslCertPath = $SPLUNK_HOME/etc/auth/sslKeysfileDEV.pem
sslPassword = certpassword
sslRootCAPath = $SPLUNK_HOME/etc/auth/blah_CA05_root.pem
sslVerifyServerCert = false   
useACK = true
sendCookedData = true

Restarted both indexers and boom.
