Merging two data sets using proxy transformations

In the following example, the Example.com company acquires Sample Corporation.

During the merger, Example.com migrates data from Sample Corporation’s o=sample rooted directory, converting Sample Corporation’s sampleAccount auxiliary object class usage to Example.com’s exampleAccount object class for entries rooted under dc=example,dc=com.

Knowing that it can take considerable time for Sample Corporation’s directory clients to become aware of the new directory information tree (DIT) and schema, proxy data transformations are created to give the Sample Corporation’s clients as consistent a view of the data as possible during the migratory period. These transformations allow the clients to search and modify entries under o=sample using the Sample Corporation schema.
