Solr Upgrade from 3.4 to 4

In order to make use of pivot feature present on Solr 4, I upgraded from 3.4.

Shall I proceed with a full reindex of the content due this upgrade or are they compatible somehow?

And regarding my client-applications that are currently accessing my solr server 3.4, will they present problem after upgrade? (The preliminary test I did they are running, seems the xml schema returned in a query response didn't changed when you don't use new features)

You need to do a full reindex if you want to use the Solr 4 index structure. Else you need to change the Lucene version in solrconfig to use the old index.

The schema will need a new field called _version_ if you want to use the Real Time Get functionality.

Other then that most things are pretty much the same for the client.
