Thanks, Erick, I had forgotten about that. I did find one short reference to it in the doc: "Be sure to run the Lucene IndexUpgrader included with Solr 4.10 if you might still have old 3x formatted segments in your index. Alternatively: fully optimize your index with Solr 4.10 to make sure it

I did the IndexUpgrade path to upgrade my 4.x index to 5.x (15 terabytes of data an growing), It wasn't an easy task to do it without downtime, IndexUpgrade doesn't work if the replica is loaded. With 12T of data re-index is like a no-no operation (the time expended to do the re-index can

Re: Next Solr Release - 5.5.1 or 6.0 ?

There's always the IndexUpgrader, one could run the 5x version against a 4x index and have a 5x-compatible index that would then be readable by 6x OOB. A bit convoluted to be sure. Erick On Thu, Mar 24, 2016 at 8:49 AM, Yonik Seeley wrote: > On Thu, Mar 24, 2016 at 11:45 AM,

Re: Next Solr Release - 5.5.1 or 6.0 ?

Does anybody know if we have doc on the recommended process for upgrading data after upgrading Solr? Sure the upgraded version will work fine with that old data, but unless the data is upgraded, the user can't then upgrade to the next major release after that. This is a case in point - the user is

Kind of a unique situation for a dot-oh release, but from the Solr perspective, 6.0 should have *fewer* bugs than 5.5 (for those features in 5.5 at least)... we've been squashing a bunch of docValue related issues. -Yonik On Wed, Mar 23, 2016 at 5:19 AM, Alessandro Benedetti

Re: Next Solr Release - 5.5.1 or 6.0 ?

Thanks Erick, I thought the same, better to wait a little bit for a 6.x migration. Let give it some time to be released and pissibly bug fixed :) I will follow your suggestion, migrate from 4.10.2 to 5.5.0, a possible 5.5.1 should be trivial to upgrade later. Cheers On Tue, Mar 22, 2016 at 4:45

Re: Next Solr Release - 5.5.1 or 6.0 ?

No real plans have been made that I know of for a 5.5.1 release. What happens is that 5.5 was cut as, potentially, the last 5x release. Some small fixes are still back-ported "just in case" there's a 5.5.1 release. As for 6.0, that's something of a moving target currently, we're still flushing
