I recently migrate ADSM from VM server to Aix server.

        1) Speed of backup is very better because Unix is a very true
             tcpip world.

        2) I installed Netware IPX drivers on my aix ADSM server because
           Novell communicate better in IPX/SPX mode

        3) I have 150 stations who backup on my server ( 65 Unix Aix and Sun,
            20 Novell station , Netware 3.11, 3.12 and 4.1, many windows,
            OS2, MAC, Linux, Dos)

        4) My database use now 2 Gb of disk

        5) I use 4 Gb to storage pool on Disk

        6) I have Tape library 8mm, 7331-201 of IBM, with 240Gb capacity
           with compression

        7) I'll add another 7331-205 in the next week

        8) When i migrate from VM to AIX, i just migrate archives files
            because i assume that client backup total data at a new times.

        9) To migrate archive files who was on 3490 cartridge, i used a
           PC to simulate retrieve all my client one by one anr archive
           on the new server. To migrate Unix archive i installed Linux
           on the PC and then retrieve and archive files.

        10 ADSM6000 is a good IBM product like ADSM VM was. All my clients
            are very satisfact.


If you have any questions, I'll be very happy to exchange with you my
experiences.
