: "We will only provide a conversion tool that can convert indexes from : the last "branch_3x" up to this trunk (4.0) release, so they can be : read later, but may not contain terms with all current analyzers, so : people need mostly reindexing. Older indexes will not be able to be : read natively without conversion first (with maybe loss of analyzer : compatibility)." ... : i dont see anything suggesting we should support any tools for 2.x indexes!
I read the sentence that sayd "Older indexes will not be able to be read natively without conversion first" sentence and assumed that was talking about ... i dunno, "older indexes". I certainly don't pretend to be an expert on an index converstion tool thta doesn't even exist yet, but the point i was trying to make in response to the users question... >>> Is re-indexing my only option or is there a tool of some sort >>> to convert the 1.4 index to 3.1 format "Index format versions change over time, and support for older formats is phased out. Solr 3.1 should be able to read your Solr 1.4 index and convert it automaticly. Solr 4.x will *not* be be able to automaticly read indexes created by Solr 1.4, but there will be a process for 'converting' your indexes. Unlike previous instances where the index format version changed when upgrading Solr, starting with Solr 4.0 this conversion will not be automatic, and will require the use of a tool." Does that sound more accurate based on your understanding? that even if the yet-to-be-built-index-conversion-tool for Solr/Lucene 4.0 can't read Solr1.4/Lucene2.9 indexes, there will still be an upgrade process from Solr 1.4 to Solr 4.0 (mainly: upgrade to Solr 3.x, let it auto convert your indexes, and then ultimately use the 4.0 conversation tool to explicitly convert to Solr 4.0) ? ? -Hoss
