Suresh Thalamati commented on DERBY-377:
----------------------------------------

Sorry , did not catch the following case earlier. 

In preparing for Upgrade section ,  Following step is not required:

1.
Force a checkpoint with the earlier version of Derby. To force a checkpoint, 
connect to the database with the older version of the Derby software and issue 
a shutdown request using the shutdown=true attribute on the database connection 
URL, as shown in the following example: 
/* in a java program */
DriverManager.getConnection("jdbc:derby:sample;shutdown=true");

--

Online backups do a checkpoint  and  users are recommend to do a shutdown 
before taking 
an offline backup. So ,  I think the above step is not needed in preparing for 
upgrade.
