LDN - Luminis Developer Network

With the recent announcement of end of support for SunONE on windows (and the myriad of problems were having post Lum IV migration) , were accelerating our plans to move to an alternative platform, most likely exchange.

Has anyone done a complete, full migration from SunONE to Exchange? I'm not so concerned with the Luminis integration at this point. Just checking to see if anyone has migrated everything (mail, address book, calendar, calendar groups, etc) successfully.

I'm also looking for anyone that is running a hybrid system (Sun + Exchange or other), but preserving a single email domain for all users.

PLEASE contact me if you have any info on these subjects.

Thanks Everyone!
