Migrating from solr8.11.3 to solr 9.5.0
Hi ,
I am plannig to migrate from solr 8.11.3 to 9.5.0 in solrcloud
architecture.
The idea is to create a new line of solrcloud 9.5 where to create the
collections present in solrcloud 8.11.3 and reindex all the content on the
new platform.
My doubt is about the config with which to create the collections in
solr9.5.
Can I keep the config present in solr 8.11.3 or do I necessarily have to
adopt the new one present in the default configs and report in this what we
defined in solr8.11.3?
Thank you
regards

I recommend checking what has changed between the versions and ensuring
that all the configs used are still valid and supported.
I would also carefully change the constants such as the Lucene match
version (https://sease.io/2021/04/lucenematchversion-in-apache-solr.html).
So, in short, there's no need to start from the new default, but also I
strongly don't recommend copying and pasting the old solrconfig.xml and
schema because stuff may not work as expected or something could silently
stop working.

I assume here that you are talking about solrconfig.xml and the schema.
Without seeing the config, it's difficult to answer that question. If
the config is not using anything that is deprecated in 8.11.3, it SHOULD
work just fine in 9.x. Anything that is deprecated in 8.x will be
removed in 9.x.
Thanks,
Shawn

Also look at the logs for warnings. Use of legacy/deprecated stuff is
often logged.
