---------------------------------------
Summary: Add a configuration upgrade tool for Solr
Key: SOLR-11229
URL: https://issues.apache.org/jira/browse/SOLR-11229
Project: Solr
Issue Type: Improvement
Security Level: Public (Default Security Level. Issues are Public)
Affects Versions: 6.6
Reporter: Hrishikesh Gadre
Despite widespread enterprise adoption, Solr lacks automated upgrade tooling.
It has long been a challenge for users to understand the implications of a Solr
upgrade. Users must manually review the Solr release notes to identify
configuration changes either to fix backwards incompatibilities or to utilize
latest features in the new version. Additionally, users must identify a way to
migrate existing index data to the new version (either via an index upgrade or
re-indexing the raw data).
Solr config upgrade tool aims to simplify the upgrade process by providing
upgrade instructions tailored to your configuration. These instructions can
help you to answer following questions
- Does my Solr configuration have any backwards incompatible sections? If yes
which ones?
- For each of the incompatibility - what do I need to do to fix this
incompatibility? Where can I get more information about why this
incompatibility was introduced (e.g. references to Lucene/Solr jiras)?
- Are there any changes in Lucene/Solr which would require me to do a full
reindexing OR can I get away with an index upgrade?
