The migration tool, dsmig, is delivered with the Directory Server Enterprise Edition 11g Release 1 (11.1.1) packages. When these packages have been installed, dsmig is located in install-path/bin.
The dsmig command must be run on the machine on which the new Directory Server instance will be located. When the command is run, a migration directory is created within the new instance directory (new-instance-path/migration). This directory is a repository for data produced by the migration, including log files and migration status files.
The dsmig command includes a set of sub-commands and options, that map to the individual migration steps described in Outline of Migration Steps. For information about the usage of dsmig, see dsmig(1M).
