------------------------------------
{quote}Eventually we would like to incorporate this tool as part of the SOLR
distribution if there is enough interest from the community.

I saw your talk in Las Vegas and think that this effort is of benefit for many.
More important than where the tool lives is that it gets exposed through
RefGuide and maintained for each version. Are you also making tooling in
Cloudera to upgrade from Trie to Point fields etc or do you use a reindex from
source strategy (guessing the latter)?
> 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
> Priority: Major
>
> 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?
