Upgrade SolrCloud with external cluster Apache Zookeeper
Hi,my name is Sandra. I am from Uruguay.
I have a three server cluster Solr 7.7 with Apache Zookeeper 3.5.5.
I want to upgrade both.
Solr 7.7 --> 8.11 --> 9.4.0
Apache Zookeeper 3.5.5 t-- > 3.6.5 --> 3.9
My questions are:
- Can SolrCloud 8.11 works with Apache Zookeeper v3.9?
- Which of both i have to upgrade first?
tks sandra

Hi Sandra,
No, it won't work. Solr 9 will still know the core was created in Solr 7,
even if you upgrade to Solr 8 in between.

I've 8.11 running with 3.9 w/o problems (but it's not in production yet).
As most people here will tell you, if you can set up a new cluster from
scratch and import the data, you'll likely save yourself some time and
headaches compared to in-place upgrading twice.

solr 7.7?

Hi Sandra,
You can't upgrade more than one major Solr version. Solr 9 will refuse to
work with a core that has ever been touched by Solr 7.
My advice for any upgrade is to set up the new version from scratch and
rebuild your index from the authoritative data source.
