We are using BES 4.1.7 and are looking to migrate to BES 5.0.2. Our environment is about 6,000 Blackberry users spread over about 4 BES domains (based on the continents - America, Europe, Asia-PAC, Canada). Each BES domain contains multiple BES servers.
We have the option of either going for an in-place upgrade of the existing servers or creating new 5.0.2 environments from scratch and then using the Transporter tool to move users across.
I was wondering what experience people had on this forum of either method and what their recommendation would be?
