How to move all documents from one collection to a new one with no routing key specified (6.3.0)

Have a collection c1 that has 400,000 documents and c2 with no documents (new collection).

No routing key is specified in either collection.

Trying to use the migrate Collections API endpoint found/described in the documentation.

Since no routing key is specified I'm not sure what to use for the split.key parameter. I have found this thread that mentions that a split.key=! should encompass all documents. This has not proven true in my tests.

Here is my attempted url: http://solr.node:8983/solr/admin/collections?action=MIGRATE&collection=c1&split.key=!&target.collection=c2&async=1

This has not worked, and I have tried many iterations of the split.key parameter with no avail. Have tried blank, a!, id!, id, compositeId and none of them have migrated any documents to the c2 collection.

How does the Migrate function work with no specified routing key? Is there a default value to use to grab all documents that will actually work?

Thank you!

Edit: since no routing key was specified the current router is compositeId as solr does that when it is not specified.

I have the same question with you. I would like to get the answer too. I only get some answer from SOLR guide.

split.key The routing key prefix. For example, if the uniqueKey of a document is "a!123", then you would use split.key=a!. This parameter is required. reference: https://solr.apache.org/guide/8_6/collection-management.html
