Question Bes Questions

Please Login to Remove!

We have Bes in our organization . BES 3.6.3.8
We wanted to put Bes 4.0 side by side with the 3.6. We have 80 users and did not want to migrate all of them at once since the Bes has to scan the mailboxes all over again. Some of my users have lots of mail and that would bog down my exchange server. Trying to set it up where i can move them in stages and decomission my old server.

Thanks to all who respond.

OK... I would love to answer your questions, but I don't see any.

FWIW, if the BES and Exchange server are close to eachother (ie ethernet only) you should be fine to move the users. I don't think that you are going to have too much of an issue as far as slowing the network or any kinda of disruption of service, other than the blackberry itself.

I say go for it. But every migration I have done from 3.X to 4 has been cutover, straight upgrade. Works well.

cd.

my suggestion is an in-place upgrade to BES 4.0 SP2, then a knife-edge cutover to new hardware with the same configuration in place. no end-user interaction or affect. if you have the second server built, its probably going to be about an hour long project. saves you money on licensing as well, so thats always a plus.

yeah but i do not want to disrupt users and want to migrate them 3 or 4 at a time.. we have had issues with scanning large mailboxes hanging our server. This is why i am taking that approach.. besides the server is old and want to get it on a new server.

Do you have IT Policy implemented? If not, I'd HIGHLY suggest doing a complete uninstall of BES 3.6 and then reinstalling with BES 4.0 on that same server - using the same SRP Identifier, SRP Authentication Key, service account mailbox, and BES virtual server name (the name of the server listed in BlackBerry Manager). You will want to export your users from the 3.6 installation prior to uninstalling. You will also want to back up the database to another location. After you install BES 4.0, you'll want to configure it with the above information from the 3.6 server and then import the users. At some point, they'll want to do an Enterprise Activation, but it is not needed. They will be working as is. Export the users from the BES 4.0 installation to a text file.

Now, at this same time, you'll have the new server with an OS. You'll go through the complete installation of BES 4.0 and patching - but you'll set the services to MANUAL. You won't select the option to Start Services at any point during your installations. The SRP, etc. will be the same as mentioned above for the old server. The services MUST NOT be started until they are stopped on the old server. Once you have completed the installation, you will want to set the BlackBerry services to manual on the old server and then turn them down. Once they are completely stopped, you can now start the services on the new server. All of the users should populate, but if they do not, you will need to import them from the text file.

If you have a local database, be it MSDE or SQL, you will need to move it, as well. There is a field in there that needs to be edited - under the ServerConfig table, it will be the MachineName field - needs to be updated to the current machine name.

Anyhow, that is the less intrusive way of doing it, imo. It would be the least impact on your users and it would migrate the server and database to new hardware. And you can still have the other server available for an uninstall and fresh install for a pre-production environment, if you wish.

You can export the IT policy to a text file. You can just re-create it and apply it to the users after you have the new server up and the users imported. I did this and it worked ok. I had a little trouble getting the policy to apply to a couple of 3.6 handhelds, but other than that. It was quick and painless. Good Luck!

policy will be pushed over-the-air no matter what, so no. i'd recomment exporting the policy from the database and re-importing it, though. less work. i believe its documented somewhere here - if not, then it is on RIM's site.
