Questions About Upgrading to Unity 4.0

[rhindle2k2]

Hi all,

I have a few questions before upgrading a server to 4.0 from 3.1.3 and installing a new 4.0 server. We currently have 7 Unity servers all running 3.1.3 with digital networking. We plan on upgrading one server to 4.0 and installing a new server with 4.0 fresh. This is the beginning of the upgrades for the entire company and my questions are as follows:

1. Will updating the AD schema when installing/upgrading to 4.0 cause any problems with the other 3.1.3 servers?

2. Since there is only one Unity service account currently with the 3.1.3 configuration, will creating the 4 new Unity accounts cause any problem or will I/should I use the current Unity service account for the unityadmin or any of the other 3 new accounts? I'd like to start from scratch with 4 new accounts and not use the current service account and migrate to the new accounts when upgrading the other servers.

3. Is there any problem with having 3.1.3 servers running in conjunction with 4.0 servers in general?

My impression is that all of the above is fine in that I would have no problem running 3.1.3 servers alongside with 4.0 servers, there should be no problem using new Unity service accounts and that updating the AD schema should not be a problem for the older servers, but I want to be certain before doing the upgrades/install.

Oh, this is all running with Exchange 2000.

Thanks for your time!

1) It's backwards compatible

2) Creating 4 new accounts will be fine.

3) You can run 3.1(x) alongside with 4.x

Do you plan on having the servers in the same dialing domain and taking advantage of any of those features it bring such as Identified Subscriber Messaging? 4.0(4) supports a larger set of Digital Networking features and 3.1(3) is pretty darn old so I really would recommend getting them both up to 4.0(4). You will have more functionality and much more stability/resiliency.

Thanks,

Keith

Thanks for the replies and suggestions! We will be upgrading all Unity servers to 4.04, but since some are in Europe and some in the US and I am the only one doing the upgrading it will have to be in pieces. :)

Thanks again for your time!
