Migrating multiple domains

All migration scenarios are essentially the same, differing only in their level of complexity, as measured by the number of domains being migrated and the trust relationships among them. The procedure covered in these topics can be used to migrate a single domain or multiple master and resource domains.

Note: Before you begin any migration process, prepare all Rational® ClearCase® hosts as described in Preparing Rational ClearCase hosts. Even though the hosts might not be migrated immediately, they are not accessible by migrated users and groups until you take this step.

Migrating users and groups
Begin by migrating users and groups from the Windows NT® domains in which they were created to new Active Directory domains.
Migrating individual hosts
When all users and groups have been migrated and no users are required to log on to the Windows NT domain, migrate Rational ClearCase hosts to the Active Directory domain.
If VOB servers cannot migrate when clients do
If any VOB server cannot migrate when its clients do and you need to preserve the clients’ ability to access VOBs on that server, you must use vob_siddump to establish a mapping between new SIDs and old ones.
