Default BES Server Migration

Please Login to Remove!

I'm looking to put together a plan to migrate V4.0.1.16 from a W2K server to a W2K3 server.
There are a few threads on here, but all seem to give different solutions etc to the question of how should a migration take place.

Is there a definative method to carry out this task, documented somewhere?

I'm lucky that there are only 12 accounts on the old server, however the users are all high ranking members of staff, who could not be without their mobile e mail etc etc, the same old story!!
They all use either XDA's or PDA's, alas they do not use Blackberry handsets.

I am also in a fortunate position where, i can run two servers at the same time, if that makes things easier.
I know that the second server's BES service cannot be started until the 1st server is turned off though.

Does / will the new BES server require similar ID credentials to the existing server (Name & IP)?

Will all this work, without the users having to reconfigure their handsets?

The migration strategy that you choose is dependent upon some of the following:
1. Current network environment - messaging system layout -
2. Available resources - hardware, software
3. Current BES version - BES server and handhelds should be considered
4. Current BES architecture - e.g. remote SQL, single-box install
Since you're going from 4.0.1.16 on a W2K server to a W2K3 server (unless I mis-read), then you don't really require an elaborate plan to do so. There's the famous "Knife-edge-Cutover" that RIM describes, plus there's multiple options described here in the forum.
No one method is best, it's just a matter of convenience in some cases and level of comfortability with the process.
You can use the second server to setup the destination point. Once you maintain the same SRP ID & Authen keys, BES server instance name and BES service account, then you should be fine. There wouldn't be any requirement to re-cradle or reconfigure devices.
If the SQL database is local, you can "detach" and "attach" to other BES server if you intend to maintain the "Single-box" install method.
If it's remote, simply point the new BES to the database during the install phase.

Thanks for the reply,
the current network layout is that of a exchange server, a seperate dedicated blackberry server, which will have SQL locally, the servers are blades, which are all new.
Yes i am taking the same version from w2k to w2k3.

Re the second server, does the name of the server & IP have to be the same as the original server?

Re SQL, which is the better option, to have the database locally or on a remote SQL box?

That is depending on the number of users. If you have more then 500 users it is better not to use MSDE. If your company has already MS SQL servers running, then it is always better to use that.
With a remote database it is easy to have more then 1 BES sharing the same database (also handy with moving to a new server, see dev).

Be aware, though, that running on an external SQL server means that if there are any major revisions to BEs that change the database schema, you will have to update the database manually.

I had to do this when I upgraded from 3.7 to 4.0.

It's not a hard thing to do, it's just something you should be aware of, to prevent problems further down the road.

ok, many thanks for you reply.

I guess the best option then seeing as the current server only has 12 users is to keep things local
