Hi,
we have a BES 4.3 i believe and are upgrading to BES 5.
what are best practices?

I am thinking a brand new vm machine, install the upgrade (if possible without ver 4.3 -- or do i need ver 4 on it first???)..
and migrate users slowly rather than upgrade the current BES and things might break.


this is done for exchange 2010 upgrade....
any suggestions or whitepaper i can follow?

thank you plenty :)

Hi,

If you are going to purchase a new BES 5 licence (SRP etc.) then I'd recommend using the Enterprise Transported to migrate users in Live mode between the 2 enviornments.

The Transporter connects to the old BB Config DB, the new config DB and the Blackaberry Administration service - you can migrate users in blocks of 20 and it takes approx. 4 -5 mins per user.

User wise, it's pretty seamless - just a brief interruption in service.

Hi,

Therefore suggestion is to create a complete new environment including a new configuration database and then migrate users from old environment to new one.

Nb. you might need to upgrade your BES 4 environment to a newer SP/MR.

Have a look at this:

Thank you,

in that case, do I need to create a new besadmin account to authenticate the new BES install while the other bes is running?

Hi,

No - you can use the same account as the Exchange permissions will be in place and you'd need to connect to both SQL instances using an account that's able to read and write to the database - i.e. the BESADmin account.

Hi.

If you have the facilities, it's always good to do this in a pre-prod environment or even as some form of POC to validate the process and accounbt permissions etc.

I appreciate that not everyone can but VMs may help considerably.

it was suggested by BES to create a new account and grant exchange permissions.
i wasnt sure if this would confuse things or make them easier.

so if i can copy BESADMIN account into new besadmin2 account and run exchange commands and ensure permissions are properly granted than it is still better to use the current??

Hi,

That would also work - you can specify separate accounts when configuring the Enterprise Transporter for SQL access purposes.
