Preparing your DB2 environment

Prior to preparing your DB2® environment, ensure that your database has been upgraded to the version of DB2 supported for your environment. For information about system requirements, go to the IBM® Support Portal at http://www.ibm.com/support/entry/portal/Planning. If you are upgrading to DB2 10.5, refer to the DB2 documentation for instructions.

Note: If you are upgrading in sharded mode, the instructions described in this section must be followed for all shards in all colonies.
