I did install 5.0.1 MR1 a little while ago and moved a group of 16 users over using the transporter tool. There were some discrepancies in the address books of 10 of those 16 users. This is a known issue in MR1 and is corrected in MR2. Once installing MR2, all the issues were cleared up.
Some FYI's for you that I haven't found documented anywhere from Novell or RIM in regards to using BES 5.0.1. BES 5, as you're aware, uses only the SOAP protocol, it no longer relies on the GW client. Sending an item from the BlackBerry on BES 5 will show the email address of the user in their Sent Items folder on the GW client
For example if I send an email to
on BES 4.1.x, in the Sent Items folder on GW it would show as Scott Smith. When on BES 5.0.1 it shows as
Also, I don't know how many of your users use categories, but when a user is added to the BES 5 server it adds categories to their GW client.
If you delete these categories from the client, they come back down again. I have a ticket open with RIM on this. It is not a major issue, but I have some users that heavily rely on categories and these cause clutter and the users yell at me.
One more issue is when a user accidentally moves their mailbox folder to the Calendar or Contacts folder in the folder list and then moves it back, the BES either doesn't receive the SOAP event or doesn't process it. Thus causing the mailbox to be missing from their folder redirection list and leaving the user to not receive mail. You can correct this by restarting the services. I have done a WireShark trace to see where the issue lies, if the BES isn't getting the SOAP event, or not processing it.
I will attach a document I typed up with more information on these steps.
These are not deal breakers, but things I wish I was aware of when I moved these users over. Most of our users are still on BES 4.1.7 mr1, but will be moved over shortly.
