+* 1.5 -> 2.0
+
+** Database upgrade
+
+The first thing the server does when upgrading from 1.5 is run the
+disorder-dbupgrade program. This is necessary to modify any non-ASCII track
+names to meet the latest version's stricter normalization practices. The
+upgrade should succeed automatically; if not it should leave an error message
+in syslog.
+
+It is strongly recommended that you back up your database before performing the
+upgrade. For example, as root, with the server STOPPED:
+ cd /var/disorder
+ mkdir BACKUP
+ cp -p * BACKUP
+
+To restore, again as root:
+ cd /var/disorder
+ rm *
+ cp -p BACKUP/* .
