Using
dsmig
to Migrate User Data
In Directory Server 5.2, data is stored in serverRoot
/slapd-
instance-name
/db
. Directory Server
6.0 stores user data in instance-path
/db
.
To migrate data automatically, run the following command:
$ dsmig migrate-data
old-instance-path new-instance-path
All suffixes are migrated by default, except the
o=netscapeRoot
suffix.
dsmig
copies the data,
the indexes, and the transaction logs. The database context, that is, the state of the database, is
not migrated.
In the new Directory Server administration model, there is no Configuration Directory Server.
This means that the
o=netscapeRoot
suffix is no longer relevant, unless your deployment
includes Identity Synchronization for Windows. By default,
dsmig
does not migrate the
o=netscapeRoot
database, unless specifically requested. To migrate the
o=netscapeRoot
database, use the
-N
option with the
migrate-data
subcommand.
For more information, see
dsmig
(1M).
Note –
During data migration, Directory Server checks whether nested group definitions exceed
30 levels. Deep nesting can signify a circular group definition, where a nested group contains a
group that is also its parent. When a group with more than 30 nesting levels is encountered,
Directory Server stops calculating the
isMemberOf
attributes for additional levels.
Each time this happens, Directory Server logs an error. You safely ignore these errors, although
you should examine the definition of the group mentioned in the error message for potential
circular definitions.
Tasks to be Performed After Automatic Migration
If you have used
dsmig
to migrate your server automatically, only the following two
post-migration tasks must be completed:
■
If you have customized user plug-ins, these need to be recompiled and added to the new
server manually.
■
If the migrated server was part of a replicated topology, see “Issues Related to Migrating
Replicated Servers” on page 52 .
