Transitioning from Solr 1.2 to Solr 1.3
Hey,
I just want to copy over my indexes from my production server running
1.2 to another test server running 1.3. Since my Index are live I can't
just stop the it. I also have 5 GB of indexes so I do not know how long
I will need to take it down. All option I read backup the index
directory using hard links. I need to copy the data. What is the best
way? I have been using google and solr wiki but haven't found a way to
do this.

We just went through this process. We simply copied the 1.2 index to the
new server (while the 1.2 server was live---responding to requests and
handling updates) and started it up with 1.3. It worked. I can't promise
that you'll have the same experience, but it's worth a try. Also, if I were
you, I'd assume that some of the documents will be lost, so I'd reindex any
recently added documents.

Backup or snapshot taken by hard links are save to copy since once Lucene
creates an index file, it will not be modified.
>From the 1.3.0 release notes:
The Porter snowball based stemmers in Lucene were updated (LUCENE-1142),
and are not guaranteed to be backward compatible at the index level
(the stem of certain words may have changed). Re-indexing is recommended.

Ok, I think I jumped the gun here. I'm not sure on this so I'll let someone
who knows more comment on this.

Copying the index may not work because the index format has changed (due to
upgrade in lucene in 1.3). Re-indexing is the only option.
