There will also be tool / mechanism to do the same on 4.0 - it is not 100% nailed down how this might work eventually but it seems to be very likely that there will be a read only support for old indexes - a merge will then build new-style segments out of old-style segments. simon -Hoss -- http://lucenerevolution.org/ ...

Re: No more trunk support for 2.9 indexes
I suppose an index 'remaker' might be something like a DIH reader for a Solr index - streams everything out of the existing index, writing it into the new one? This works fine if all fields are stored (and copy field does not go to a stored field), otherwise you would need/want to start with the orignial source. ryan
No more trunk support for 2.9 indexes
Hi, I'm sure there are good reasons for the decision to no longer support 2.9 format indexes in 4.0, and not have an automatic upgrade as in previous versions. Since Lucene 3.0.2 is 'out there', does this mean the format is nailed down, and some sort of porting is possible? Does anyone know of a tool that can read the entire contents of a Solr index and (re)write it another? (as an indexing operation - eg 2.9 - 3.0.x, so not repl) Thanks, Peter

So converting an index would be faster than remaking it? Dennis Gearon Signature Warning EARTH has a Right To Life, otherwise we all die.

Re: No more trunk support for 2.9 indexes
If a tool exists for converting 2.9-3.0.x, it would likely be faster. Do you know if such a tool exists? Remaking the index, in my case, can only be done from the existing index because the original data is no longer available (it is transient network data). I suppose an index 'remaker' might be something like a DIH reader for a Solr index - streams everything out of the existing index, writing it into the new one?
