We've been running solr 4.10.3 in production for years with simple master/slave replication. We're at a point where upgrading to 5.3 makes sense, but we're trying to do so in the easiest way possible. The current setup looks like this:
4.1_master => 4.1_slave
That being said, does anyone know if it is possible to seed the 5.3 instance via replication from the slave? Like, do the indexes differ and would it work to do chained replication like this:
4.1_master => 4.1_slave => 5.3_slave
If not, an anyone suggest good documentation for the 5.3 upgrade?
