Elasticsearch会在升级时自动更新Lucene索引吗?

[英]Does elasticsearch automatically update the lucene index on upgrade?

I want to upgrade elasticsearch from 0.90.1 to 1.1.0. 我想将elasticsearch从0.90.1升级到1.1.0。 It is unclear if elasticsearch will automatically reindex the data to the new Lucene version (used in 1.1.0). 尚不清楚弹性搜索是否会自动将数据重新索引到新的Lucene版本(在1.1.0中使用)。

Should I reindex my data or elasticsearch can do it automatically? 我应该重新索引我的数据,还是Elasticsearch可以自动进行索引?

It will upgrade your indexes automatically, but you should still back up your data. 它将自动升级您的索引,但是您仍然应该备份数据。
