Does LDAP support versioning of data?

[<mjc@home.com>]

Hello,

I am wondering if LDAP supports the versioning of directory sturctures
(schemas) and the associated data. As an example, if I have a directory
structure that looks a certain way one day, can I label the schema and its
data as, say version 1.0. The next day I change my schema slightly, call
it version 1.1 and then migrate as much of the data that I can from the
version 1.0 directory to the version 1.1 directory?

Anything close to that?

If not, anyone know of other products that may?

Thanks,
Mark
