[~WebHomer],

Internally {{CdcrReplicator}} forwards the request to target collection in 
target cluster via conventional UpdateRequest, which supports alias. Alias 
should definitely work for {{target}} collections in CDCR, need to confirm the 
same for {{source}}. Check in the logs once, {{Forwarded X updates to target 
collection Y}} in source and {{/update}} in target.

> My company uses Solr aliases to limit the configuration changes that we need 
> to support.
> The CDCR configuration seems to accept an alias for either the source or 
> target collections, and no errors show up in the log, but no data is 
> replicated if the source or target is an alias and not an actual collection.
> I see that aliases are not even mentioned in the CDCR documentation. It seems 
> to me this should either work or throw an error.
> It should be documented one way or another
