RE: Index format difference between 4.0 and 3.4

[Latter, Antoine]

We didn't have to re-index when we upgraded - but if you're using a 
master/slave setup, you won't be able to replicate from a higher version to a 
lower version - old solr cannot read the new indices.

Subject: Index format difference between 4.0 and 3.4

Hi All,

We are using Solr 1.4.1 in production and are considering an upgrade to newer 
version.

It seems that Solr 3.x requires a complete rebuild of index as the format seems 
to have changed.

Is Solr 4.0 index file format compatible with Solr 3.x format?

Please advise.

Thanks
Saroj
