How Long Will an Upgrade Take

Upgrading to Version 11.8.0 can involve significant changes to iProcess Engine 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 could have an impact, and the complexity of their interaction, for example, the amount of data in your system, the configuration of your database system, and the hardware setup you are running.

Warning

One factor that can significantly impact the duration of an upgrade is enabling case data normalization. Case data normalization is a feature that is used to make case data searching more efficient, and therefore faster, by enabling the database to do simple string comparisons instead of type conversions. If you are upgrading from an iProcess Engine version that does not already have case data normalization enabled, you can choose to enable case data normalization when you run the installer (see Enable Case Data Normalization). If you choose to enable case data normalization, the upgrade process has to create a value for the field_value_N column for every row in the case_data table. (This column holds a normalized value of the field_value contents.) Because the upgrade process has to perform this operation on every case of every procedure in the database, this operation can take a significant amount of time if there are large numbers of cases on the system.

TIBCO therefore strongly recommends that you test the upgrade before performing it on your target system, either on 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.
