SolrCloud 4.8.0 upgrade
Hi All,
I have a SolrCloud cluster with 3 server, I would like to use stats.facet,
but this feature is available only if I upgrade to 4.10.
May I simply redeploy new solr cloud version in tomcat or should reload all
the documents?
There are other drawbacks?
Best regards,
Vincenzo

Hi,
I'm seriously thinking to upgrade, but how? Could I upgrade one instance at time or should I stop all the instances and upgrade and restart everything?
Ciao,
Vincenzo

Solr/Lucene are supposed to _always_ read one major version back. Thus
your 4.10 should be able to read indexes produced all the way back to
(and including) 3.x. Sometimes "experimental" formats are excepted.
In your case you should be fine since you're upgrading from 4.8..
As always, though, I'd recommend copying your indexes someplace just
to be paranoid before upgrading.
Best,
Erick

Thanks for your answers, I looked at changes and we don't use
DocValuesFormat.
The question is, if I upgrade the SolrCloud version to 4.10, should I
reload entirely all documents?
Is there a binary compatibility between these two versions reading the
solar home?

Look at CHANGES.txt for both Lucene and Solr, there's always an
"upgrading" section for each release.
Best,

Support for the Disk-format for DocValues was removed after 4.8, so you should check if you use that: DocValuesFormat="Disk" for the field in the schema, if I remember correctly.
