Migrating an Essbase Application Across Servers Using Migration Wizard (Native Security)


Purpose


This tutorial shows you how to migrate an Essbase application from one server to another using Migration Wizard.

Scenario


In this tutorial, you migrate an Essbase application from an Essbase Release 7.1.0 server (localhost:1425) to a Release 9.3.1 server (WIN3KB). Both servers are running Essbase native security.

Prerequisites


Before starting this tutorial, you should:
1.
Have both an Essbase Release 7.1.0 server and an Essbase Release 9.3.1 server installed and running.
2.
Utilize Essbase native security on both servers.
3.
Have an Essbase application on the Release 7.1.0 server available for migrating. This tutorial migrates an application called Mexcorp.

Usage Notes


The following points apply to applications migrated using Migration Wizard:
1.
Only application and database objects and user/group security are migrated . No data is transferred.
2.
Objects and security on the source server are unchanged. Migration Wizard makes copies on the target server.
3.
Source and target servers may be on different operating systems. For example, you can migrate an application from a Windows to a Unix server.

Examining Source and Target Servers


1.
From Administration Services Console in the navigation panel, double-click the Release 7.1.0 server node localhost:1425 and expand Applications to reveal the Mexcorp application.

2.
Expand the Mexcorp application to reveal the Mexsales database, including the database outline, calculation script CalcMex, and rules file LoadMex.

3.
Expand the localhost:1425 Security node, right-click Users, and from the drop-down list, select Display users table.

In a subsequent step, we will select to migrate user JCanseco, shown here in the source server Users table.

User JCanseco has filter access to the Mexsales database. This security privilege will be preserved during the migration.

4.
On target server WIN3KB, expand the Security node and openthe Users table.

5.
On target server WIN3KB, user JCanseco is not yet represented.

Selecting Source and Target Applications


From the Source application on Analytic Server drop-down list, select Mexcorp. In the Target application on Analytic Server text box, enter Mexcorp. Finally, select Replace target objects if they exist and then click Next.

Selecting Individual Users to Migrate


Ensure that user JCanseco is displayed under Selected Users. If not, select user JCanseco in Available Users and use the arrow button to move the username to Selected Users.

Click Finish.
When the migration is complete, a message is displayed in the message panel of Administration Services Console.

Examining Migration Results


1.
In the Navigation panel, expand the target server node (WIN3KB) to reveal the migrated Mexcorp application. If Mexcorp is not displayed, right-click Applications and select Refresh application list.
Screenshot for Step
2.
In the Navigation panel under the target server node (WIN3KB), expand Security , then right-click Users and select Display users table.
Screenshot for Step
The target server (WIN3KB) users table is displayed, showing that user JCanseco has migrated from the Release 7.1.0 server to the Release 9.3.1 server.
Screenshot for Step
3.
Optionally, review access privileges for user JCanseco on the target server (WIN3KB). Permissions should reflect filter-level access to the Mexsales database through filter jcanfilter.

Summary


In this lesson, you learned how to migrate an Essbase application from one server to another using Migration Wizard, where native security was in force.
