Mike Matrigali updated DERBY-3721:
----------------------------------


I agree with myrna, if you are attempting to use a cloudscape 5.X database with 
derby it is not going to work, and we should mark
this JIRA entry as invalid.  

Cloudscape was a closed source db, and thus the derby developers can't do 
anything to help with an automatic upgrade.  
There may be generic jdbc level tools that will allow you to unload from one db 
and put the data into another db.

Derby only supports soft and hard upgrading among the various derby versions.  
There are some deep
storage level differences between the format of the underlying files between 
the two versions (even if the naming and location
of the files look similar), really the only upgrade path is to
export the data using your cloudscape software and reload it into a new derby 
db.

> An application uses cloudscape database. It requires migration to latest 
> version of derby.
> While checking the binary compatibility of the database with different 
> versions of derby, I observed the following.
> Cloudscape and  Derby Database created before and in 10.1x versions are 
> compatible across versions - All versoins are able to connect to and operate 
> on the application's DB.
> When the same database is accessed with derby versions 10.2.x and above, 
> following exception is getting thrown.
> java.sql.SQLException: Failed to start database 'dbelec', see the next
