minor upgrade support (e.g. 11.4.5 to 11.4.6)

The current upgrade process mentioned in TIBCO documentation is the same as a full installation as it installs a new version without retaining library/configurations of the current version.

This process also happens to be the same for major upgrades (e.g.: 10.10.2 to 11.4.5) and minor upgrades (e.g.: 11.4.5 to 11.4.6).

We provided a workaround to compensate for the lack of a complete upgrade solution via a mechanism that performs a backup on the current version and restores it after the new version is installed.

This is a time consuming and costly operation, which is not feasible for frequent minor upgrades.

Our requirement is that TIBCO provide a process to support upgrade from a lower version to a higher version instead of a fresh install, with minimal downtime and with library/configurations retained.

A ticket with Case Id-02091409 already exists for this requirement.

For a minor upgrade, we want a solution to upgrade node manager and server packages.

This would allow customers of Spotfire enterprise solution to upgrade to latest packages frequently without major impacts.
