I was trying the Demo application from 4.7.2 on an index created by 2.9.1. I get a org.apache.lucene.index.IndexFormatTooOldException exception. I tried the upgrader tool. Same exception again.
Is there an upgrader tool that can work with a 2.9.1 tool? Or Do I have to build one? Any guidelines would helpful Thanks, Suresh -----Original Message----- From: Buddhavarapu, Suresh [mailto:suresh.buddhavar...@emc.com] Sent: Friday, May 30, 2014 1:13 PM To: java-user@lucene.apache.org Subject: RE: Lucene Upgrade from 2.9.x to 4.7.x Thanks Xiaolong.
