DB2 Post-Installation Migration Tasks

After the installation completes, you should migrate your instances by running the db2imigr command. The db2imigr command checks that your instances can be migrated and then performs the actual migration to the Version 7 format.

To migrate instances, including the Administration Server instance, to a format useable by DB2 Version 7, you must run the db2imigr command by performing the following steps:

1. Log in as user with root authority.
2. Enter the db2imigr command as follows:

   /usr/IBMdb2/V7.1/instance/db2imigr [-d] [-a AuthType] [-u fencedID] InstName
   

   where:

   -d

   Sets the debug mode that you can use for problem determination. This parameter is optional.

   -a AuthType

   Specifies the authentication type for the instance. Valid authentication types are SERVER, CLIENT, and DCS. If the -a parameter is not specified, the authentication type defaults to SERVER. This parameter is optional. The authentication type of an instance applies to all databases owned by the instance.

   Note:

   Although authentication type DCE is a valid authentication type for an instance, you cannot specify this type of authentication using this command. For more information, refer to the Administration Guide.

   -u fencedID

   Is the user under which the fenced user-defined functions (UDFs) and stored procedures will execute. This parameter is required.

   InstName

   Is the login name of the instance owner.

Once you have migrated all of your instances to the Version 7 format, you are finished the migration process.
