This topic describes when and how to perform recommended MIMIX-specific steps while performing a standard upgrade of the IBM i operating system (slip-install, where the IBM i release is upgraded without a restore of the user libraries). Performing these recommended steps can help ensure that MIMIX products start properly once the operating system upgrade is complete.

The following table indicates which procedures are needed for different upgrade scenarios. Use these instructions in conjunction with the instructions provided by IBM for upgrading from one IBM i release to another IBM i release.

Table 1. IBM i operating system upgrade scenarios and recommended processes for handling MIMIX during the upgrade
To upgrade	Perform these procedures
Backup system only	Perform the preparation steps described in Prerequisites for performing an OS upgrade on either system. Follow the procedure in MIMIX-specific steps for an OS upgrade on a backup system.
Production system only	Perform the preparation steps described in Prerequisites for performing an OS upgrade on either system. Perform one of the following procedures: If you need to maintain user access to production applications during the upgrade, perform a planned switch as described in MIMIX-specific steps for an OS upgrade on a production system with switching. Your production operations will be temporarily running on the backup system. If you have more flexibility with scheduling downtime, you can perform the upgrade without switching as described in MIMIX-specific steps for an OS upgrade on the production system with-out switching.
Both backup and production systems	Perform the preparation steps described in Prerequisites for performing an OS upgrade on either system. Upgrade the backup system first following the MIMIX-specific steps for an OS upgrade on a backup system. By doing this first, you can ensure that the backup system supports all the capabilities of the production system and you can work through problems or custom operations before affecting your production environment. Once you have the verified that the backup system is upgraded and operating as desired, perform one of the following procedures to upgrade IBM i on the production system: If you need to maintain user access to production applications during the upgrade, perform a planned switch as described in MIMIX-specific steps for an OS upgrade on a production system with switching. Your production operations will be temporarily running on the backup system. If you have more flexibility with scheduling downtime, you can perform the upgrade without switching as described in MIMIX-specific steps for an OS upgrade on the production system with-out switching
