----------------------------------
Summary: Cannot find instructions for upgrading from one 5.x
release to another
Key: SOLR-8296
URL: https://issues.apache.org/jira/browse/SOLR-8296
Project: Solr
Issue Type: Bug
Components: scripts and tools
Affects Versions: 5.3.1
Reporter: Shawn Heisey
I'm trying to upgrade a Solr install on Linux from 5.2.1. The current install
was installed with the install_solr_service shell script.
This command doesn't work:
{code}
./install_solr_service.sh
/index/src/lucene_solr_5_3/solr/package/solr-5.3.2-SNAPSHOT.tgz -d /index/solr5
-s solr5 -p 8982
{code}
I get this message:
{code}
ERROR: /etc/init.d/solr5 already exists! Perhaps Solr is already setup as a
service on this host?
{code}
What I was hoping for was another directory in /opt, the symlink /opt/solr5
changing to point at the new directory, and a new init script, with the
installer noticing an existing solr.in.sh and other files in /index/solr5, and
not touching them.
When I installed 5.2.1, I used the same command, with the older install script
and the 5.2.1 tarball.
There is an "Upgrading Solr" section in the reference guide, but it just talks
about differences that might require config changes, not an actual procedure.
I do not know whether we need a separate upgrade script or an upgrade option
for the current script.
