Hello Mike,

We just completed a complete conversion to V3 ADSM this past month.
So far, we haven't experienced any major bugs.  We are currently
backing up Novell (15), NT (10), OS/2(1), and RS/6000 SP2 Nodes (32)
with no serious problems.  Enhancements to the client GUI's is worth the
upgrade. We also saw a significant performance boost since the upgrade.

I can offer the following comments:

1.  Print and read the README files as the install guide is
    full of bugs.
2.  Be careful when enabling the central event logging function
    (ie., sending client events to the server activity log) as
    this can overrun your database in a hurry.  Increase the size
    of your database before doing this.
3.  The ADSM scheduling function continues to be the weak link
    in the product.  We will be using a third party tool due to
    the many problems encountered.
4.  Document your device config. in AIX as you will need to
    reconfigure after the install.
5.  The UNIX GUI is gone for ADSM, the web browser piece works OK
    but needs a little work.

We are currently adding a second server to handle Oracle database
backups as files tend to be large (>250 MB).  The server stresses
with large files.

Hope this helps.
