What is the process of upgrading search and index cluster?

New Member

Hi All,

I need to upgrade a search and index cluster. Please advise if anything is missing and my understanding is correct.

Process:
Upgrade the master node.
Upgrade the search head tier.(Rolling upgrade)
Upgrade the peer node tier. (Rolling upgrade)

( Maintenance and rolling upgrade of each server)

When we are integrating Peer nodes( indexer nodes) we have to stop search cluster and
My expectation is it will take 1 -2 hours to finish all the indexer nodes. During that time alerts and searches may fail
and the ingestion keeps working.

Forwarders and DMC: What is the suggestion.

Thanks,

NP

It looks like you are talking about an indexer cluster, not a search head cluster? Are you following the steps in Upgrade an indexer cluster in Managing Indexers and Clusters of Indexers?

For search head cluster upgrade docs, see Upgrade a search head cluster in the Distributed Search manual.
