2.2.2 High number of migratable applications
An application is termed
migratable
when there is a direct way to migrate the
application to a Linux client, either by using a Linux version of the application or
using a Linux based alternative.
As described in more detail in 4.7, Unmigratable applications on page 81,
applications that do not migrate well to Linux complicate the migration to a large
extent. This also means that more migratable applications will lead to easier
migration.
Before performing a migration and handling the unmigratables, some
organizations will try to move away from applications that do not migrate easily.
The best way to do this is to move the application to a portal based application.
This will not only facilitate moving to a Linux client, but then the application will
also not be a problem in any future migrations.
2.2.3 Organizational readiness
Even if all other factors in the migration are favorable, an organization that is not
ready for a migration will still be unsuccessful. An organization that is ready can
be defined as:
Having end users that are ready and able to move to another client
Having administrators and support staff that are enthusiastic about the
migration and knowledgeable about the technology you are migrating to
Having procedures in place that will streamline the handling of problems
during and after the migration
These factors are discussed further in Chapter 3, Organizational and human
factors planning on page 27.
One of the most important factors is that the migration has to be carried by the
administrators. The people who have to manage the clients and infrastructure
after the move can make or break the migration. Getting system administrators
and support staff behind the migration is one factor that can become very
important in the decision process.
2.3 Migration goals
Not all migrations are the same. While eventually migrations will have a goal of
replacing all desktop clients in an organization with Linux clients, most early
migrations will serve as pilot projects and only migrate a part of the desktops.
