Hello,  
I'm trying to migrate to a new server and a new cluster.  
My Data pipeline's output is being now on the new server, and I'm starting to receive data. However I can't restore my old data using \_reindex neither Elasticdump because I receive an error "only write ops with an op\_type of create are allowed in data streams"  
and whenever I add the option :  
"op\_type": "create"  
The I receive data but indexed with the current date and not with the date on the old server.
