3 – The Migration Process
Understanding
the OSx system
Understanding
what needs to be
migrated
Designing the
PCS 7 application
Determining how
to create PCS 7
configurations
No two migration projects are alike. However, all such projects
follow the same basic steps.
The first step is to understand the OSx system to be migrated. That
means doing an evaluation of the system to understand how OSx
has been applied. What features of OSx are being used and how
much configuration data there is must be determined. Appendix D
has a questionnaire that can provide the questions that need to be
answered.
A migration results in a major change in the way an organization
controls and manages a process. The migration presents that
organization with a chance to re-evaluate their control strategy and
algorithms. Their existing strategy was partly designed around the
feature set of OSx. Now they will be using PCS 7 which does
things differently, provides new features that didn’t exist before,
and may not have features that match some features of OSx.
In some cases, they may want to replicate the OSx system using
PCS 7. In other cases they may decide to re-engineer the way they
do things to better fit within the PCS 7 paradigm.
Once a decision is made as to what must be migrated, and what will
be newly created, the PCS 7 way of doing it must be determined.
Then, an order in the way the PCS 7 project is created has to be
decided. The number of stations, whether redundancy is
implemented, and what PCS 7 features are used determines the
order of the steps in creating the PCS 7 project. The PCS 7/505
Setup Guide discusses the proper order for creating a project.
When the new PCS 7 project is finally implemented, configurations
for each feature will have to be entered into the system. These
configurations can be entered manually, or through bulk import
mechanisms. Some features, such as 505 tags, can only be
configured via a bulk import mechanism. Other features, such as
trend configurations can only be configured manually. Finally,
there are features, such as action requests, which can be configured
