I am trying to migrate from a SolrCloud Cluster which has 1 shard and

In prod today we can run on 1 AZ even if the other 2 can be down.
Something to keep in mind:
Solr itself might function with only one, but if it does, it will be
read-only because Zookeeper cannot be set up to function properly in an
event where two out of three data centers go down. To survive two
failures, you would need to have five ZK servers, each in a different AZ.
