Prerequisites to Migrating a Single Directory Server
Instance From 5.1
Before migrating from a 5.1 server instance, ensure that the following prerequisites are met:
■
Directory Server 6.0 must be installed. The new server can be installed on the same machine
as the existing server or on a dierent machine.
■
Ensure that the new machine has sucient local disk space to house binaries and databases
for both the old and new servers, and also enough extra space to hold LDIF les containing
the entries in all existing suxes. You can estimate the local disk space required as
somewhat larger than the following calculation.
local space required=2*(space for existing server) + (space for LDIF files)
Prerequisites to Migrating a Single Directory Server
Instance From 5.2
Before migrating from a 5.2 server instance, ensure that the following prerequisites are met:
■
Directory Server 6.0 must be installed. The new server can be installed on the same machine

■
Ensure that the new machine has sucient local disk space to house binaries and databases

the entries in all existing suxes. You can estimate the local disk space required as
somewhat larger than the following calculation.
local space required=2*(space for existing server) + (space for LDIF files)
■
If you are using the automatic migration tool, the following two prerequisites must be met:
■
The existing server instance must be stopped cleanly.
■
If the new server is located on a dierent machine, a complete image of the original
server instance must be created on the new machine. This includes all schema les,
conguration les, security les, and database les, in an identical layout to the original
server root.
To determine whether you should use automatic or manual migration, see
“Deciding on
Automatic or Manual Migration” on page 28
.

If your Directory Server deployment includes Identity Synchronization for Windows, you
must uninstall Identity Synchronization for Windows before migrating to Directory Server
6.0. For information about migrating Identity Synchronization for Windows, see
