Upgrade Performance and Timing
Upgrading to Version 11.9.0 can involve significant changes to iProcess data and data structures. The upgrade process is therefore complex, and can take a significant amount of time to complete if the system being upgraded has a large amount of case data.
TIBCO cannot provide an estimate of how long the upgrade will take because of the number of customer-specific factors that can have an impact, and the complexity of their interaction, such as, the amount of data in your existing system, the configuration of your database, and the hardware setup you are running.
TIBCO therefore strongly recommends that you test the upgrade before performing it on your target system, either in a representative production environment, or using a copy of your production system. This will allow you to determine how long the upgrade is likely to take, and to identify any specific factors that may affect the success or duration of the upgrade.
