AD Schema Extension and TSPConversion

We have two (2) Unity 3.1(3) servers running Digital Networking. We will be performing separate upgrades to Unity 4.02 on these servers with about 2 weeks lag between upgrades. I would like to confirm that the schema extend that occurs during 4.02 upgrade process on first server will not cause issues with our second server still running on 3.1(3).

Also, will 4.02 TSP upgrade process automatically convert multiple TSP CCM clusters and their respective port assignments? We have 2 CCM cluster defined under TSPs, each with a respective pool of voice ports. Will these automatically be converted with same parameters during upgrade?


Re: AD Schema Extension and TSPConversion

The 4.X schema extensions are fully backwards compatible with 3.X. You won't run into any issues during the lag.

During the upgrade your current TSP information is maintained. No reconfiguration will be required.

Hope these help,

Hello -

We are running Unity 3.1(5) and have already applied the Unity 4.0 schema changes to our forest. Just an FYI - upon reviewing the log files (*.ldif) from the schema extension for errors, you might see errors that indicate an object (s) has already been added to AD. That's because the schema has to include all of the objects needed for Unity in case a new user is doing this for the first time. So many of those you will already have in your AD database.

Re: AD Schema Extension and TSPConversion

Hi Ginger,

Yes, we did see these error messages after our install in the Lab and we were questioning whether they indicated a failure in the Schema extend process. The end messages in our log indicated that the Shema extend was successful but it is still good to know that these errors do not indicate a critical failure in the process.
