Re: is there an easy way to upgrade from Solr 4 alpha to 4.0 final?
If it is a problem, you should be able to just stop your cluster and nuke that file in zookeeper, than startup with the new version. - Mark On Jan 8, 2013, at 5:09 PM, Markus Jelsma wrote: > I am not sure this applies to alpha and final but i do think upgrading from > 4.0 to 4.1 will give you trouble regarding data in Zookeeper.

RE: is there an easy way to upgrade from Solr 4 alpha to 4.0 final?
I am not sure this applies to alpha and final but i do think upgrading from 4.0 to 4.1 will give you trouble regarding data in Zookeeper. At least clusterstate.json has changed. Check the appropriate Jira issues between alpha and final regarding Zookeeper or test to make sure it works. -Original message- > From:Shawn Heisey > Sent: Tue 08-Jan-2013 22:50 > To: solr-user@lucene.apache.org > Subject: Re: is there an easy way to upgrade from Solr 4 alpha to 4.0 final? > > On 1/8/2013 2:27 PM, eShard wrote: > > I just found out I must upgrade to Solr 4.0 final (from 4.0 alpha) > > I'm currently running Solr 4.0 alpha on Tomcat 7. > > Is there an easy way to surgically replace files and upgrade? > > Or should I completely start over with a fresh install? > > Ideally, I'm looking for a set of steps... > > Thanks, > > For the most part, you should be able to just replace your .war file, > erase the tomcat deployment directory (where it extracted any war > files), and restart tomcat.

Is there an easy way to surgically replace files and upgrade? Or should I completely start over with a fresh install? Ideally, I'm looking for a set of steps... Thanks, For the most part, you should be able to just replace your .war file, erase the tomcat deployment directory (where it extracted any war files), and restart tomcat. If you used any additional jar files from the Lucene/Solr distribution (dataimport handler, additional analyzers, etc., and any dependent jars) then you would have to also delete the old versions and copy the new versions. If you have custom Lucene/Solr components, that is where you're most likely to run into trouble. There were a number of internal Java API changes from alpha to beta to release that might affect those. It's possible, but not super likely, that you might need to make config changes. From what I've seen, the basics were mostly unchanged from ALPHA to release. There should be a list of things that changed in CHANGES.txt that you can peruse for items that might affect your config. It should go without saying, but I'll say it anyway: You should have enough redundancy so that you won't be down even if the upgrade goes badly on your secondary server(s), and you should also have good backups of *everything*, including your index files. Thanks, Shawn
is there an easy way to upgrade from Solr 4 alpha to 4.0 final?
I just found out I must upgrade to Solr 4.0 final (from 4.0 alpha) I'm currently running Solr 4.0 alpha on Tomcat 7. Is there an easy way to surgically replace files and upgrade? Or should I completely start over with a fresh install? Ideally, I'm looking for a set of steps...
