To import additional languages, you can choose between the following options:

• You import additional languages during the upgrade.

  We recommend that you choose this option since importing new languages during an upgrade is a highly efficient process and is preferable to importing a language into a production system after an upgrade. In this way, you can avoid any sequencing problems arising from Support Packages included in the upgrade, or Support Packages you need to import after the upgrade.

• You import additional languages after the upgrade.

  We recommend that you only use this option if the system contains the Support Packages for the language archives you are using. This is the case if you did not include any additional Support Packages in the upgrade, or did not import any additional Support Packages after the upgrade. For more information, see the Language Transport documentation, or SAP Note 352941 .

The upgrade procedure itself only offers to update existing languages. You cannot install any new languages during the upgrade. However, you do have the option of classifying new languages in the SAP system before the upgrade with transaction SMLT, and importing them during the upgrade. For more information about this procedure, see SAP Note 322982 .
