7signal Sapphire Deployment Guide Release 3.0
9 UPGRADING SAPPHIRE
Every official software delivery from 7signal contains Release Notes. It is always advisable to
read the Release Notes for the latest information on the software.
However, upgrade instructions seem to vary per releases in such proportion that it is justified
to deliver upgrade instructions separately from the software package. This piece of
information is provided by 7signal Services and Operations.
The upgrades can be divided into three categories:
1) Major version upgrades;
2) Minor version upgrades;
3) Hotfix upgrades.
9.1 Major version upgrade
Major change is likely to contain a completely new technology or a profound change in the
ways of interaction. Database changes are likely. All the components are to be updated.
9.2 Minor version upgrade
Similar to major version upgrade except that minor releases just typically combine the agreed
new features.
9.3 Hotfix upgrade
There should not be any change in the database. Currently all the Sapphire elements are
updated. 7signal explores a way to lighten the upgrade process regarding the hotfixes.
The hotfixes aim to solve a single problem, malfunction or similar that could potentially stop
the system from producing measurements.
