General administrative tasks

• Determine the order in which to migrate post offices. Use this order to determine your migration schedule.
• Decide which types of cc:Mail and Organizer data to migrate. Migrating certain types of data, such as bulletin boards and Organizer information may require additional planning and preparation.

• Estimate the amount of disk space required to migrate cc:Mail mail boxes.
• Decide how your cc:Mail gateways will map to Notes domains for routing mail to external mail systems.

Lotus Notes and Domino preparation tasks

• If you did not perform a custom installation of the Domino Administrator client that installed the cc:Mail Domino Upgrade Service, run the Domino 6 Administrator client again and choose the cc:Mail Domino Upgrade Service.
• From the Domino Administrator machine, map a drive to the location of the cc:Mail post office you are migrating users from.
• Back up Domino information.
• Log in to Lotus Notes with a Notes ID that has "Create database access" on the Mail server.
• Verify that you have access to the certifier IDs and passwords for the Domino organizations and organizational units where you are registering users.
• Verify that you have Editor, Designer, or Manager access rights to the Domino Directory on the Registration Server.
• If you anticipate migrating additional mail for users after registration, configure the mail file ACLs to ensure that you retain the appropriate access rights. Use the migration option Add administrator to mail file access control list.
• (Optional) Set default registration preferences.
• (Optional) Create a Notes group that you can add migrated users to.
• From the Domino Administrator or from the Domino Administrator machine, close all applications, except for Lotus Notes, and close any Notes databases.

• Clean up the cc:Mail message store. Instruct users to archive or delete mail that they no longer need. Consider limiting the amount of mail that users can migrate.
• Clean up the post office directory.
• Familiarize yourself with how the cc:Mail Domino Upgrade Service parses cc:Mail names formats. Certain name formats and characters may not be converted correctly during migration. To ensure that all migrated users are created with appropriate Notes names, it may be necessary to edit certain names either before or after migration.
• Make sure all users being migrated have assigned passwords. If the cc:Mail password is blank, null, or zero-length, the migration of the user will fail. If you have a cc:Mail user with this type of password, change it to a non-blank password in cc:Mail.

  Note The cc:Mail Domino Upgrade Service does not support the selection in the Migration Options box "Generate random passwords for users with no passwords."

• Take the post office off-line to make it inaccessible to users.
• Send any in-transit cc:Mail messages. Post office mail queues are not migrated. Clear all Post Office Message Queues and Router Express calls with Send Only. Run Link products and run the Organizer scheduling agent.
• Back up the cc:Mail post office being migrated.. This backup preserves the state the post office was in before you run the maintenance utilities.
• Verify the integrity of your post office by running regular maintenance. See the Lotus cc:Mail Administrator's Guide for more information about using the cc:Mail maintenance tools.
• (Optional) Delete unnecessary messages in the cc:Mail Message Log, Trash, and so forth, using the CHKSTAT command for DB6 or MSGMGR for DB8. After deleting messages, run RECLAIM to recover disk space from these deleted messages.
• Create a second backup of the post office that preserves the state the post office was in after you ran the maintenance utilities.
• If you are also migrating Organizer information for users, prepare users to upgrade Organizer information.
• After you complete the preparation tasks, migrate your Organizer users first. When migrating Organizer data, add the Organizer users to the registration queue before any other users.
