Hi All,
Currently we are using Solr 5.2.1 on production server and want upgrade to Solr
7.7.2. We are using solr 5.2.1 from last 5 years, we do have millions of
documents on production server. We have Solr cloud with 2 shards and 3 replicas
on production server.
I have upgraded Solr 5.2.1 to Solr 6.6.6 , it is upgraded successfully on my
local machine.
Now I am trying to upgrading Solr 6.6.6 to Solr 7.7.2. I have upgraded all 6
solr instances one at a time to Solr 7.7.2. I am getting below error. One shard
(with 3 replicas) is upgraded successfully bu =t the another shard is giving an
error (please refer below image). Though one shard is upgraded, I can not do
anything with that. I think issue is due to old indexes or documents.

I am struggling from last few days to migrate solr 5.2.1 to Solr 7.7.1.
Can you please share your inputs or please assist me?
Thanks,
Yogesh Chaudhari
