I am wondering if anyone has experience migrating from BES with Exchange to BES/ZBC with Zimbra and can offer some insight. Meaning we have a functioning BES with Exchange. We have migrated email to Zimbra. Now I want to get this BES server working with Zimbra. Is it best to wipe the BES install and start from scratch or can I just modify the config? Will I need to do anything with the phones as they will point to the same BES they have been all along? Thanks for any assistance.
