Resolution: Invalid
> Multi-DC not working between 1.1.10 and 1.2.4 version
> -----------------------------------------------------
>
> Key: CASSANDRA-5684
> URL: https://issues.apache.org/jira/browse/CASSANDRA-5684
> Project: Cassandra
> Issue Type: Bug
> Components: Core
> Affects Versions: 1.2.4
> Environment: Linux
> Reporter: Ananth Gundabattula
>
> We wanted to upgrade to a higher version of cassandra ( a custom build of 1.2.4 ) from current cassandra version 1.1.10.
> The way we wanted to upgrade is to build a new cluster and enable multi-dc replication; rebuild and switch the application layer to the new cluster. This enabled us to have the least downtime.
> However, I was not able to get a multi-dc going between these two versions. I followed pretty much the instructions here ( for the 1.2.4 version ) http://www.datastax.com/documentation/cassandra/1.2/index.html#cassandra/operations/ops_add_dc_to_cluster_t.html. I tried enabling multi-dc using these instructions for the 1.1.10 cluster http://www.datastax.com/docs/1.0/initialize/cluster_init_multi_dc
> Mixing both the approaches did not work either. Specifying a 1.2.4 node as one of the 1.1.10 cluster seed nodes caused errors in the startup of 1.2.4 node. The error was not an exception but a message looking like this in the logs : ClusterName mismatch from /10.xxx.xx.xx DC1!=DC2
