About the migration strategy, you may have to choose between reindexing all the data or migrating your current indexes.
the IndexUpgrader tool will be able to handle that. You will have to migrate your indexes from 4 to 5, then 5 to 6, and finally 6 to 7. https://lucene.apache.org/solr/guide/7_6/indexupgrader-tool.html <https://lucene.apache.org/solr/guide/7_6/indexupgrader-tool.html> If you still have your original data, then the reindexing option is better. And even more if you plan to use the new field options available, which means changing the schema.
