Solr collection name changed to n1

Hi, 

we are migrating Solr from 6.6 to 7.7.

Now it looks like the collection name has somehow changed from "collection_shard_replica_1" to "collection_shard_replica_n1" which means we have to export and import all collections... and that's a lot of data.

 Many thanks for any hints. 
 

Ralf
