Upgrading multiple master and resource domains
Use this procedure when Rational® ClearCase® users
and groups are members of more than one Windows NT® domain and you use proxy
groups to enable users from these domains to access a common set of VOBs and
views. The domains can include resources, users, and groups or can be master
domains trusted by resource domains.
To upgrade multiple master and resource domains:
- Prepare Rational ClearCase hosts,
as described in Preparing Rational ClearCase hosts.
- If you do not have a backup domain controller online for each of
the master and resource domains during the upgrade, stop Rational ClearCase on
all server hosts to prevent Rational ClearCase operations
during the upgrade process.
- Use the procedures defined by Microsoft® to perform an in-place upgrade
of the first Windows NT master domain to an Active Directory
domain. Upgrade the domain in which the Rational ClearCase users
group is defined before you upgrade the domains in which the proxy groups
are defined.
- Upgrade the remaining master domains.
- After the master domains are upgraded, you can begin to upgrade
the resource domains. If you do not alter existing
trust relationships between domains that have been upgraded and those that
have not, you can upgrade the resource domains in any order and on any schedule
that is appropriate for your organization. Make all upgraded domains members
of the same forest. This allows you to use Active Directory universal groups,
as described in Using active directory universal groups.
- After the upgrade of a resource domain is complete, shut down and
restart all Rational ClearCase hosts
in that resource domain.
- After all domains have been upgraded and the Active Directory domain
has been converted to native mode, follow the procedure in Converting proxy groups to
eliminate proxy groups and domain mapping.
Convert the Active Directory domains to native mode after the
upgrade is complete, so that you can use an Active Directory universal group
to eliminate the need for proxy groups and domain mapping.
