reindex a lucene index with solr
i have a lucene index that some fields of docs are indexed with custom
incremental gaps and all fields are stored too(not only indexed).
i need to import this docs to solr cloud.
is there any way to automatically rebuild this docs for importing in solr
with costum gaps by some thing likes converter.

Then you'll have to re-index probably after you set up your new collections.
If you have stored _all_ your original fields you could query from
your 4x and index to your SolrCloud, but it'd be best if you could
just reindex from the original source.
Best,
Erick

thanks for your guides Erick
before this i use solr v4.10.3 in a cluster of 40 searcher (solr instance)
each with about 40 cores.
now i want to migrate to solr cloud v6.5.1 i design my own custom policy
for document routing(default mode of routing) between shards an i have
about 1000 shards at start time.
i think by your way it is not possible because of routing method for update
documents in future solr could not find old document to update it with new
document.

What you haven't told us is whether you need to shard or not. But
there's no difference between the index built for stand-alone Solr and
SolrCloud.
So just create your SolrCloud instance, probably single shard, 1
replica with the appropriate configset. Then shut that down and copy
the index from your stand-alone Solr to the replica's index directory.
Then start Solr back up. You should be fine.
Now do whatever you need to do to build out your SorlCloud instance.
If you need more shards use SPLITSHARD. If you need more replicas use
ADDREPLICA etc.
Best,
Erick
