OK, I was thrown off by your use of "schema", I thought
you were talking about schema.xml....
Anyway, assuming you have some kind of loop that pages
through the documents via Solr, gets the results and then
sends them to another Solr server... yeah, that'll be slow.
You have the "deep paging" problem here.
I'd consider dropping into Lucene to spin through the
documents, fetch them and then assemble what you need
into a new SolrInputDocument that you then send to your
new server.
You really aren't moving any "interesting" data. By that I mean
by the time things go through your intermediate code, they're
pretty much primitive types so the fact that the various Solr
indexes have different schemas really isn't relevant.
Best

Thanks ..
i need to index data from one solr to another solr with different analyser
..
Now i am able to do this by querying from solr which will be index into
another solr
NOTE: As the field which i need to reindex is stored so it is easy by as my
index has 31 lakh record it is taking lot of time .. (suggest me for
better performance)
Thanks and Regards,

Why would you want to? This seems like an
XY problem, see:
http://people.apache.org/~hossman/#xyproblem
See the "confFiles" section here:
http://wiki.apache.org/solr/SolrReplication
although it mentions solrconfig.xml, it
might work with schema.xml.
BUT: This strikes me as really, really
dangerous. I'm having a hard time
thinking of a use-case that this makes sense
for, so be very cautious. Having an index
created with one schema and searched
on with another is a recipe for disaster
IMO unless you're very careful.
