So if you deploy Solr using the "provided" zookeeper, then it will be managed in tandem with your SolrCloud. If you want the Zookeeper Cluster's lifecycle to be independent of the Solr lifecycle, you will need to manage it separately.
I would recommend in that case to use the Bitnami Zookeeper Helm chart rather than the Zookeeper Operator's offering.
https://artifacthub.io/packages/helm/bitnami/zookeeper
You would install that by itself, and then find the Zookeeper connection String.
Then in the Solr helm values file, you would use that as the "zk.address" option (and not provide any "zk.provided.*" option).
See the solr helm chart's options for more details: https://artifacthub.io/packages/helm/apache-solr/solr#zk-options
from solr-operator.
If i had started with inbuilt ZK, would the above approach of specifying zk.address for a standalone ZK will still work?
I would like to retain the data in the solrCloud when cutting over to new ZK.

You could call the BACKUP API in order to backup the content from Zookeeper, then RESTORE once you have the new cluster and ZK installed. Or you can find one of the Zookeeper commandline utilities out there (search for it) which will let you backup/restore the content of ZK.
