Upgrade Prerequisites
- The ISR component hosts are properly running on the Oracle Linux Release 7.2 - 7.7 OS
- Access to the following
upgrade tar files from the
ISR component hosts:
- isr-Index-<release#>-upgrade.tgz
- isr-Dashboard-<release#>-upgrade.tgz
- isr-rss-<release#>-upgrade.tgz
- isr-Face-<release#>-upgrade.tgz
- Have access to the Ruby 2.6 rpm ( ruby-2.6.3.el7.centos.x86_64.rpm).
- For the duration of the maintenance window, all call traffic is stopped on all sites and outside client access to the Dashboard and API services is prohibited.
Note:
The following instructions assume the recommended "isradm" Linux user has sudo permissions.WARNING: The upgrade process for each component includes a critical backup step that copies important host configuration, ISR application configuration, ISR application platform configuration, ISR application data, encrypted keys, keystores, and log files to a temporary directory before consolidating these copies into a compressed set of files for a potential rollback situation. This backup step requires additional disk space to successfully write the files, and a warning prompt is displayed to detail concerns and recommend an option to mount an additional drive if disk space may be an issue. Oracle strongly recommends you consider these details and the recommended option carefully before continuing with the upgrade. For more information about mounting remote storage, see Chapter 22, Shared File System Administration from the Oracle Linux Administrators Guide Release 7.
