You use items in the Conversion Settings dialog box when converting an Essbase Server to EPM System security mode:
Administration Server Location—Enter the machine name and port number for the Essbase Administration Server to which Shared Services will communicate. This information is required for the Oracle's Hyperion® Shared Services Console to assign calculation and filter access and application access type for users.
Password creation settings—For native Shared Services users, specify how the passwords should be created for the Shared Services users when they are migrated:
Auto-generated—Automatically generates new passwords for users being migrated to Shared Services. The passwords are recorded in the text file specified in the text box. You must specify the extension for the file as .txt. You can also browse to the location of an existing password file to append new passwords to it.
Use native user name as password—Assigns the native user name as the password for each user being migrated to Shared Services. During migration, the user name is converted to an all lowercase password. For example, a native user named "Mark" will have "mark" as their password after migration.
Password and Confirm password—Specifies and confirm, respectively, a new password for all users created in Shared Services. You must specify the same password for all users being migrated.
