Hi all,
We use SOLR-6.5.1 and we have very strange issue. In our collection index
size is very different from server to server (33gb difference):
1. We have index size 82Gb in serverX and 49Gb in serverY
2. ServerX displays 82gb used place if we run "df -h
/opt/solr/Xxx_shardX_replica1/data/index"
Shawn, my impression is that you WILL be able to upgrade a 5.x index to 6.x and
then to 7.x for use with 7.x. So your wiki page is a bit too strict here.
But if you ever want to upgrade to 8.x, that version will require the "first
created" version to be 7.0 or later, so you'll need a full reindex
