Whoa: Starting embedded zookeeper? Almost all production systems have an external Zookeeper ensemble. Did your old system connect to an external Zookeeper? You really need to solve that problem first. My guess is you’ve (perhaps inadvertently) changed how Solr is started. You have to straignten that out first.
As to where the indexes are, they should be somewhere under SOLR_HOME, usually in a directory with some name like collection1_shard1_replica_n1, collection1_shard2_replica_n12 etc. There may be multiple ones of this.
