Is there a migration guide or some such thing? Is there a way to install over a given installation so you don't obliterate things like source directories and installed files? Or would I have to back up on disk and tape and reinstall apps and config files? Are the name database files the same for BIND? Is the Sendmail config file the same? I run a web site with two or three dozen clients, so I can't just rip up the software at my whim. I run Apache web server, Sendmail, POP mail, Majordomo, wwwstats, ghostscript, BIND, etc. >> 3.

Yes, I studied the man pages, and found howling errors in the Blocksize and Block count options. Thank God I have SunOS man pages, too... So after futzing around with these parameters, using nrst0, I managed to dump my three significant partitions onto one DAT. Then, when I went to restore them to the new disk, I rewound the tape, restored with nrst0, and after restoring the first partition, when I went to restore the second one, restore gave me several errors about not being synchronized with the beginning of the dump or something... a tape mark? I'm sorry I didn't write it down. I was in a frenzy at that point and I just did a disk-to-disk dump|restore. So, how do you restore multiple volumes from one tape? Is there some trick to it? Thanks again. - JohnR -- John R. Haggis haggis@cesium.com
