Anyway, those who have been doing Microsoft or PC networking
for a few years have probably experienced many previous migrations.
You possibly migrated to NT 4, and from there to every service
pack. Most service packs were, in effect, major system upgrades
frequently resulting in unforeseen difficulties and requiring
careful testing and planning. If you still run Windows NT today,
then you are facing a very expensive and forced migration to Windows
On the other hand, migrating to Linux is easier in many ways because
reliable support is available. With Linux, "reliable support"
means not only being able to get the help you need to solve your
current problems, it also means that you are empowered to prevent
such problems from happening again in the future.
Also, think of it this way -- what is all that expensive Windows
NT training worth now that Windows 2000 is here? And was it you
or Microsoft who decided when those skills would become obsolete?
Linux skills remain applicable for as long as you choose to have
software around, and there is rarely any need to upgrade more
than a few components at any one time.
Windows forced you to a new directory scheme, a complete new suite
of mail, Internet and other servers, and also demands enormous
hardware resources. What degree of pain will Windows 3000 impose?
In comparison, Linux offers a very attractive migration path.
How to Migrate
If you are reading this document, you probably already know why
you should migrate to a Linux-based system. It's the "how" of
doing such a migration that can often be overwhelming. Here are
some quick tips to keeping the scope of the task to a manageable
scale. The key here is to avoid trying to do everything at once.
Don't migrate everything at once. Frequently, the best
way to handle a migration is to phase NT out of the server
area first, then to later concentrate on the workstations.
Avoid application development. It is always tempting to
fix obviously bad programs during a migration. It is far
better, however, to have multiple stages in a migration,
between which you can address application issues.
Linux does more, so use its capacities. Linux can do things
that are impossible with NT and other systems, and can also
save you both time and money.
Use fewer, more open, protocols. The larger the number
of protocols you use in your networks, the larger the network
