After you migrate to EAServer 6.0:
Restart the server to activate new bindings and settings for migrated entities.
Ensure that all migrated entities run successfully.
Consider shared resources such as databases. You have migrated to EAServer 6.0, but if you leave the version 5.x server running, both versions of the application may be running against the same resource.
To use the same port numbers as 5.x, you must shut down EAServer 5.x for your listener profiles, change your EAServer 6.0 port numbers, and restart the 6.0 server.
Synchronize any cluster migrated from 5.x.
Manually migrate entities as necessary. See “Manual migration”.
Configure the migrated entities as nesessary.
Modify class loader settings to include non-J2EE packages that were removed from applications before migrating.
Remove the jdbc2_0-stdext.jar file from the lib subdirectory of your EAServer 6.0 installation. EAServer 6.0 is J2EE 1.4 compliant and supports JDBC 3.0. Removing this file helps avoid ClassCastException errors.
