Migrating Leaf Networks First
Migrating leaf networks first reduces the impact of the migration on the IPX
routing infrastructure of the network, and it allows the administrator to focus
efforts on specific sites. However, since the backbone is the last portion of the
network migrated, administrative costs may not be offset as quickly.
The steps below describe how to migrate a network from IPX to IP starting
with the leaf networks first.
1 Identify the nodes and links that form the backbone of the network.
2 Select and upgrade/install some servers in the backbone to serve as
Migration Agents.
3 Select the leaf portion of the network to be migrated. This may be a group
of segments connected to the backbone via a WAN link. Migrate the
selected portion of the network following the steps outlined in “Migrating
a Section of the Network” on page 42.
4 Repeat Step 3 until all networks connected to the backbone are migrated.
5 Migrate the backbone section using the steps outlined in “Migrating a
Section of the Network” on page 42.
The following figure shows how the steps above are applied in a sample
network.
