>This script will copy instances (data and configuration) from the old

>copied safely.  The new instances will not be started by migration,
>but can be started after running migration by doing
>
> service $pkgname start

>WARNINGS

>You will not be able to use the console or Admin Express to manage
>instances that have been migrated.  You will be able to use the web
>applications such as the Directory Server Gateway, Directory Express,
>and Org Chart.
>
>If you have configured your main database or replication changelog
>database to use separate partitions for log files and index files,
>this configuration will not be migrated.  All of your data
>will be copied to the standard FHS location
>/var/lib/$pkgname/slapd-INSTANCE/db (or cldb).
