We have about 6,000 users spread over 4 BES domains at the moment, and are looking to upgrade to BES 5.0.2.
The toss up is between creating new BES farms and using the Enterprise Transporter tool to migrate users across, or an in-place upgrade.
I had a couple of questions
i. For new BES 5.0 servers, does anyone know what the recommended specs are? What takes up most resources (CPU, memory etc)?
ii. If anyone performed an in-place upgrade or enterprise tool migration, would they mind sharing any common problems they encountered, just so we can be aware? I would really appreciate that!
