Verify your NetWare schema
before merging trees
Do you have plans to merge two or more NDS trees? Are you planning to install
NDS 8 on your cool new NetWare 5 server? If either one of these tasks is on your
to-do list, save yourself some time, and a few headaches, by ensuring that
you've got the latest schema version installed on your servers.
What's the schema?
The schema is a set of rules that determines what types of objects can exist in
an NDS tree. It also regulates these objects' possible locations in the NDS
tree, as well as their attributes.
Each version of NDS has its own base schema. However, developers can extend the
schema to include their own objects. If you don't have the same schema version
on each server, objects that are defined by a later schema version will not have
been defined in an earlier version. For example, a NetWare 4 schema version will
not define ZENworks objects.
Before you merge
Before merging NDS trees, you must ensure that the schema versions are the same.
DSMerge will not allow you to merge trees with different schema versions. You
must also upgrade the schema before installing NDS 8 on a NetWare 5 server if
the master replica is stored on a NetWare 4 server. The master replica on the
NetWare 4 server will be unable to replicate to the NetWare 5 server until the
schema versions are the same.
Upgrading the schema
Upgrading the schema is a relatively easy task. Do the following on the server
that is holding the master replica:
