We have a BES 2.2.4 server with a separate 2.2.4 attachment server. We also have a BES 4.02 server with the attachment server on the same 4.02 box. I would like to upgrade the 2.2 attachment server to 4.0 prior to upgrading the BES 2.2 server. RIM tells me the 4.0 attachment server will be compatible with the 2.2. BES server, but I am not 100% convinced of this. Has anyone done this and have real world experience that it actually does work?
A remote attachment server simply runs a service on the box. All that's required is the configuration on the BES server ponting to the attachment server. There really is no other interaction than that. It should be fine.
Attachment server compatibility
