Is re-indexing required after copying solr.data index files from old node?

Hi All,

We are trying to replace an old node with a new node which is solr enabled.We are copying all the system, data and solr index files under ~/cassandra/data/ from old node to the new node.

Do we need to re-index the solr cores on the new node again or only copying the index files to new node will take care of indexing?

Thanks,

Rakesh

@rakeshgouda1992_96602 Copying all data files from the node getting replaced should be sufficient. However if you detect inconsistencies for whatever cause, it might be necessary to reindex. You'll need to do your own tests to verify that the indexes are valid. Cheers!
