is there a way using 1.4 index at 4.0 trunk?

Hello, I'm using solr 1.4 version. I want to use some plugin in trunk version. But I got IndexFormatTooOldException when it run old version index at trunk. Is there a way using 1.4 index at 4.0 trunk? Thanks, Jason -- View this message in context: http://lucene.472066.n3.nabble.com
