Hi, I am trying to upgrade the Solr version from 5.4.1 to 8.11.2. I had installed solr 5.4.1 on my production server which consists of a lot of data which takes a lot of time to reindex data for solr 8.11.2. I have tried the IndexUpgrader tool but it's not working because I am upgrading Solr between two major versions(not consecutive). Is there any faster way to upgrade the solr version from 5.4.1 to 8.11.2 without affecting my production?
Could you help me please? Thank you!
