Default BES migration to new upgraded server

Please Login to Remove!

Hi All,
I have a customer who is hammering out the exact details on migrating from a 3.6 BES to a 4.1 BES. The existing 3.6 servers currently use SQL Server 2000 and run on a Exchange 2003 A.D. domain. As SRP's are limited the plan was to simply bring the 4.1 online with the same SRP and then migrate the users but I do understand that this will cause Blackberry to cease functioning (2 servers using the same SRP).

So for this particular operation I was thinking this scenario:

1. Install SQL server on the new server
2. Move the old BES database to the new SQL server 2000 Instance
3. Install the new BES server v 4.1 making sure to use the same Exch 2003 account, same SRP, etc. but yank it's LAN cable before it finishes rebooting
4. Disable all BES services on the 4.1 server
5. Reconnect the new BES 4.1 server (services disabled)
6. Stop BES on the 3.6 server
7. Start BES on the 4.1 server

Questions:

As I am moving to a new version of BES will this work?

Will the initial install attempt of BES 4.1 fail if I input a SRP that is currently in use on the network? (note: I won't try to test the connection or hit the RIM)

Will the users need to re-cradle with the upgrade?

Will the users lose any files/email with the upgrade action?

Any help would be most appreciated and thanks!
