no servers hosting shard: shard2
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.

Want to upgrade Solr 5.2.1 to 7.7.2
Hi All, Since 2015 we are using Solr cloud for search. We are using Solr 5.2.1 now we want to upgrade Solr 5.2.1 to Solr 7.7.2. Along with Solr we are using Zookeeper 3.4.6 and wanted to upgrade it to Zookeeper 3.4.10. We have huge data stored in existing Solr and need to maintained while migrating to Solr 7.7.1. We have installed Solr 5.2.1 & Zookeeper 3.4.6 on windows server, for installation we have used NSSM tools. We have installed 3 Zookeeper on 3 instances , 6 shards and 9 solr nodes on 3 different instances. Can you please share procedure to upgrade Solr 5.2.1 to Solr 7.7.2 on windows without affecting existing solr data (want to maintained)? Thanks, Yogesh Chaudhari
