Re: Index upgrade from 1.4.1 to 3.1 and 4.0
Regardless of what anyone here says, you need to try it. 3.1 should be able to read 1.4.1, yes. One the format is switched to 3.1, you can't go back and read it with 1.4.1. This is why you want to upgrade your Slaves first, then your Master (if you have them -- I remember we spoke a while back and that wasn't the case back then).

Re: Index upgrade from 1.4.1 to 3.1 and 4.0
Thanks Otis, but this is not my case. Most of my fields are not stored , but I do have the original data in case I need to reindex. My question is do I need to? If my 1.4.1 can be read by 3.1, I assume 3.1 can continue to write to it? In that case, I continue assuming that 4.0 will know how to read only the new segments, and if I optimize it, than I will have only one new segment, created by 3.1, thus readable by 4.0. It makes sense to me, the only question is if my guesses are right:-) Thanks.

Re: Index upgrade from 1.4.1 to 3.1 and 4.0
Hi Ofer, We recently helped a customer go through just such an upgrade (or maybe even from 1.3.*). We used a tool that read data from one index and indexed it to the new index without having to reindex the data from the original sources. All fields in the source index were obviously stored. :) Otis Sematext :: http://sematext.com/ :: Solr - Lucene - Nutch Lucene ecosystem search :: http://search-lucene.com/ - Original Message > From: Ofer Fort > To: "solr-user@lucene.apache.org" > Sent: Fri, April 22, 2011 10:34:26 AM > Subject: Re: Index upgrade from 1.4.1 to 3.1 and 4.0 > > Nobody? > Am I the only one in need of upgrading an index that was created with 1.4.1? > > Thanks for any info > Ofer > > On Friday, April 22, 2011, Ofer Fort wrote: > > Hi all, > > While doing some tests, I realized that an index that was created with > > solr 1.4.1 is readable by solr 3.1, but nt readable by solr 4.0. > > If I plan to migrate my index to 4.0, and I prefer not to reindex it > > all, what would be my best course of action? > > Will it be possible to continue to write to the index with 3.1?

Re: Index upgrade from 1.4.1 to 3.1 and 4.0
Nobody? Am I the only one in need of upgrading an index that was created with 1.4.1?

Index upgrade from 1.4.1 to 3.1 and 4.0
Hi all, While doing some tests, I realized that an index that was created with solr 1.4.1 is readable by solr 3.1, but nt readable by solr 4.0. If I plan to migrate my index to 4.0, and I prefer not to reindex it all, what would be my best course of action? Will it be possible to continue to write to the index with 3.1? Will that make it readable from 4.0 or only the newly created segments? If I optimize it using 3.1, will that make it readable also from 4.0? Thanks Ofer
