I think you are going in the wrong direction in your upgrade path…. While it may *seem* simpler to go from master/slave 6.6.6 to SolrCloud 6.6.6, you are much better off just going from master/slave 6.6.6 to SolrCloud on 8.7 (or whatever is the latest).
SolrCloud has evolved since Solr 6 by two MAJOR versions, and is much more robust with so many fixes. Today, I suspect very few folks who know the innards of Solr are actually still familiar with the 6.x line! This is also a really good opportunity to relook at your schema as well, and make sure you are using all the features in the best way possible. > On Jan 6, 2021, at 1:40 AM, Ritvik Sharma <ritvik.s...@gmail.com> wrote: > > Hi Guys, > > Any update. > > On Tue, 5 Jan 2021 at 18:06, Ritvik Sharma <ritvik.s...@gmail.com> wrote: > >> Hi Guys >> >> Happy New Year. >> >> We are trying to move to solr cloud 6.6.6 as we are using same version >> master-slave arch. >> >> solr cloud: 6.6.6 >> zk: 3.4.10 >> >> We are facing few errors >> 1.
