public class IndexMigration
extends Object

IndexMigration implements a utility that migrates a Jackrabbit 1.4.x index to version 1.5. Until version 1.4.x, indexes used the character '￿' to separate the name of a property from the value. As of Lucene 2.3 this does not work anymore. See LUCENE-1221. Jackrabbit >= 1.5 uses the character '[' as a separator. Whenever an index is opened from disk, a quick check is run to find out whether a migration is required. See also JCR-1363 for more details.
