Currently there is one main Solr instance installed in the DDB-Dev-Network: on ddb-di-05. This instance serves as the main search server for the develop and master backend deployments.

These instructions are only for updating this instance. Various prerequisites to running a solr instance are not covered as they have already been set up on this server.

To update this instance the following steps should be performed:

Download the new Solr version

1	`wget https://mirror.synyx.de/apache/lucene/solr/X.Y.Z/solr-X.Y.Z.tgz`
