Important Note: It is important to understand the status of the configuration files during an upgrade process. The configuration files for the system reside within the currently executing Bank. During the upgrade process, a backup of the configuration from the currently running Bank is automatically made. After the new software is written into the new Bank, the configuration is then restored into the new Bank so that when you boot into the new Bank it has the same configuration that is in the currently executing Bank. However, if you then boot into the new Bank and make changes to the configuration in the new Bank, those changes will not reside in the old Bank. If you wish to return to the old Bank and you have made changes to the configuration, you should back up the configuration on the new Bank, boot into the old Bank, and then restore the backup. This process is outlined in the section on Backup and Restore.
