[DDI-users] DDI conversion

[Wendy Thomas]

Basically yes. DDI-C is backward compatible so no changes were made to
existing objects .The mapping to 3.1 objects is correct for all the
previously existing objects. What you are missing are;
a) New 2.5 objects and their related 3.1
b) 2.1 to 3.2
c) 2.5 to 3.2 (note that 2.5 was published before 3.2)

To do the second you need to refer to the 3.1 to 3.2 change log and see if
any of the items mapped from 2.1 to 3.1 have changed in 3.2.

2.5 contains only a change log from 2.1 to 2.5.

While it would be good to have a 2.5 to 3.1 or 3.2 it has not been done as
far as I know. If someone has I'd be glad to review it and we could get it
posted. I don't see it getting to the top of my "to do" list any time soon
or even not so soon.
