made a stable move to Solr 6.6 , things are fine and no red flag with 6.6. I'll
follow for any new updates on this.

> Key: SOLR-11537
> URL: https://issues.apache.org/jira/browse/SOLR-11537
> Project: Solr
> Issue Type: Bug
> Security Level: Public(Default Security Level. Issues are Public)
> Components: SolrCloud
> Affects Versions: 7.1
> Environment: Solr 6.2.1 & Solr 7.1.0
> Reporter: Atita Arora
>
> We have a Solr cloud running with multiple collections with each collection
> split over 6 shards with replication factor of 2.
> We would want to use some advance features like LTR and advance analysis
> using heavily nested documents, thus we wished to upgrade.
> So we attempted to upgrade one of the nodes from the cluster to Solr 7.1.0.
> Ideally when restarted the node happily became the part of cluster while when
> attempted to ADDREPLICA through API and through Admin console we ran into the
> below issue :
