+### CAUTION![]()!
+
+This release requires database dump and restore for upgrading. Here are
+upgrade sequence.
+
+In this release, mroonga has two changes that requires database
+recreation:
+
+1.  Storage engine name is changed to "mroonga" from "groonga".
+2.  Groonga's native time data value are used for DATE, DATETIME and
+    TIMESTAMP type values.
+
+We need to modify dumped database to change "ENGINE=groonga" in "CREATE
+TABLE" SQL. Here are upgrade sequence.
+
+We dump a database that uses mroonga:
+
+    % mysqldump MY_MROONGA_DATABASE > database-groonga.dump
+
+We convert storage engine in dump file:
+
+    % sed -e 's/^) ENGINE=groonga/) ENGINE=mroonga/' database-groonga.dump > database-mroonga.dump
+
+We confirm that ENGINE=groonga only in CREATE TABLE is replaced with
+ENGINE=mroonga. We need to check `@ ... `@ line includes CREATE TABLE.
+If the line includes CREATE TABLE, the hunk will be a change for CREATE
+TABLE:
