Currently, I am planning a migration between machine which under True64UNIX. The new machine will run with higher version O/S. My question is, is there any solution on migrating one machine to another which with different O/S version? My goal is keeping minimum impact to the users.

Good afternoon all,
I'm a bit stuck... I honestly don't know very much about Unix let alone UnixWare for that matter. I have a system that's very old and could fail really at any time. I have another server I'd like to move everything to yet I don't know what's possible. The current server is... (2 Replies)
I run SCO 5.0.7v in ESXi 5.5 and am looking at ways to increase performance. I notice that the VM hardware is still set to 4 and wondered if there was an advantage in raising it or will this cause issues? (0 Replies)
Looking for a modern server to run SCO OSR 5.0.7 without VM (native), h/w must have manufacturers warranty.
Requirements would be to accommodate light loads of up to 15 users, app does not take more than 30 - 40 MB of RAM and data stored takes up to 15 - 20 GB, no internet connections... (3 Replies)
Hello Friends/AIXgurus,
When you have time, could you please look into below. We're planning to migrate AIX LPARs on to new Hardware.
Requirement: Migrate AIX LPARs from POWER 6 to POWER 8 Hardware (*everything should run as is after the transition)
Below is our thought process. Ours... (5 Replies)

dumpon
DUMPON(8) BSD System Manager's Manual DUMPON(8)NAME
dumpon -- specify a device for crash dumps
SYNOPSIS
dumpon [-v] special_file
dumpon [-v] off
dumpon [-v] -l
DESCRIPTION
The dumpon utility is used to specify a device where the kernel can save a crash dump in the case of a panic.
Calls to dumpon normally occur from the system multi-user initialization file /etc/rc, controlled by the ``dumpdev'' variable in the boot
time configuration file /etc/rc.conf.
The default type of kernel crash dump is the mini crash dump. Mini crash dumps hold only memory pages in use by the kernel. Alternatively,
full memory dumps can be enabled by setting the debug.minidump sysctl(8) variable to 0.
For systems using full memory dumps, the size of the specified dump device must be at least the size of physical memory. Even though an
additional 64 kB header is added to the dump, the BIOS for a platform typically holds back some memory, so it is not usually necessary to
size the dump device larger than the actual amount of RAM available in the machine. Also, when using full memory dumps, the dumpon utility
will refuse to enable a dump device which is smaller than the total amount of physical memory as reported by the hw.physmem sysctl(8) vari-
able.
The -l flag causes dumpon to print the current dump device or _PATH_DEVNULL ("/dev/null") if no device is configured.
The -v flag causes dumpon to be verbose about its activity.
IMPLEMENTATION NOTES
Since a panic(9) condition may occur in a situation where the kernel cannot trust its internal representation of the state of any given file
system, one of the system swap devices, and not a device containing a file system, should be used as the dump device.
The dumpon utility operates by opening special_file and making a DIOCSKERNELDUMP ioctl(2) request on it to save kernel crash dumps. If
special_file is the text string: ``off'', dumpon performs a DIOCSKERNELDUMP ioctl(2) on /dev/null and thus instructs the kernel not to save
crash dumps.
Since dumpon cannot be used during kernel initialization, the dumpdev variable of loader(8) must be used to enable dumps for system panics
which occur during kernel initialization.
FILES
/dev/{ada,da}?s?b standard swap areas
/etc/rc.conf boot-time system configuration
SEE ALSO fstab(5), rc.conf(5), config(8), init(8), loader(8), rc(8), savecore(8), swapon(8), panic(9)HISTORY
The dumpon utility appeared in FreeBSD 2.1.
BUGS
Because the file system layer is already dead by the time a crash dump is taken, it is not possible to send crash dumps directly to a file.
