Default Designing upgrade options for BES 4.1.6 to 5.0.1

Please Login to Remove!

Hey guys,
I've been attempting to design an upgrade solution for my company's BES 4.1.6 server to BES 5.0.1. I've gone through the upgrade guide and believe what I'd like to do is an cutover upgrade process, meaning that I install a new 5.0.1 server with different SRP credentials and move users over using the BES Enterprise Transporter. While I understand that the in place upgrade of the DB is easiest, what I really would like to know is, 1) is it possible to have two BES servers up at the same time using two different versions? 2) Move users from one environment to the other using the BES enterprise transporter from 4.1.6 to 5.0.1? 3) Has anyone actually upgraded like this successfully?

Thanks,
Garo

If I understand the process correctly you would need to build your BES 5 server in a new BES Domain (new configuration database), and then use Transporter to move users from the 4.x server to the 5.x server.

I followed this process when I built a new BES 5 server in another country. I then used the Transporter to move about 60 users from our BES 4.1.6 server in the US to the new 5.0 server. It worked really well.

Thanks a lot man. Did you have any issues with moving I.T. policies or having BB clients connect?

We had to create the IT Policies and Groups on the new server to match what we had on the 4.x server. We did not find a way to export and then import to the new server.

From the Transporter tool choose the appropriate IT Policy and Group before you add users to the list.

We had a problem with a couple users that had the 4.3 device OS. We had to have them upgrade to the 4.5 device OS before moving them.

What version of 4.3 did you have?

I'm not sure what you mean by "what version of 4.3". Carrier? Device model? Not really sure.

The devices we moved were from UK providers. It's been about 6 months since I did this move and I don't have notes on the providers that had the 4.3 OS. There were only a 1-3 devices max. The rest were 4.5 or better, so it wasn't a big issue for us.

From re-reviewing Transporter documentation it appears that the solution is to upgrade to 4.5 or better of the device OS or that you might have problems with using the Transporter to apply the desired IT Policy once the device is moved to the new server.

Just completed a migration of around 600 users from 4.1.7 to 5.0.2 using the transporter and it worked extremely well. New BES servers and fresh SQL 2008 database.

Having the new environment up in parallel with the current system allowed us to test IT policies and work out any bugs before the migration. I would also recommend running a stand alone BAS server.

We just performed 4,400+ users moving from 4.1.6 to 5.0.1 in 3 days with the transporter tool, worked beautiful.

Migrated 1000 users from 4.1.6 to 5.0. My move was similiar to yours, but RIM recommended to me to create a new DB and not upgrade the DB. Went without a hitch.
