Software Upgrade Support
Active Upgrade technology supports the installation or upgrade of application software
that meets the following criteria:
•
The application's executable files, configuration files, and temporary files (for
example, cache files) reside on internal system disks that are mirrored with RDR.
•
The application's persistent data files reside on separate data disks, either internal
or external. (Data volumes that reside on the same physical disk as a system
volume are not supported.)
•
The application's installation or upgrade utility does not involve changes to
files or databases on the data disks while the system is in split mode. (For
example, the utility cannot create new databases or convert existing data
records to be compatible with the new version of the application).
The Upgrade Side has no access to the data disks while the system is split.
