Hi Wael, Getting configs and data out of Cloudera's HDP is about the same as moving data between any 2 Solr clusters.
Moving configs is going to be the easy part. If you're currently using Solr in SolrCloud mode, then your configs all live in ZooKeeper. Recent versions of Solr have a utility for downloading and uploading collection configs from ZooKeeper: run "bin/solr zk" for more details. Without checking, I'm not sure whether this tool is available as far back as 4.10.3. But the way that the tool works, I believe the current version would work against an older SolrCloud install, so you can download a more recent version and use the tool to extract and reupload your configs where you need them. If you're _not_ using SolrCloud, your collection configs will be on disk, and moving them between installs is as simple as moving them on disk. Much more complicated is getting your index data into your new install. If you stay on the same Solr version, you should be able to re-use your existing index files. That said, recent releases have seen Solr make strides in becoming cloud/docker aware, or at least tolerant. 8.3.1 or 7.7.2 will likely be easier to manage on docker than 4.10.3. Additionally, 4.10.3 no longer receives any security backports from the community, and hasn't for some time. It's worth considering whether that offers enough benefits to be worth the pain of reindexing.
