Upgrading SCO Openserver 5.0.4 to 5.0.7

Hello, i am interested in the steps needed to upgrade 5.0.4 to 5.0.7
and the amount of time needed to successfully complete. Also any
gotchas i could look out for would be great to know.

Hi, Drew.

Start with a clean install of 5.0.7 - don't try the upgrade option 
during the IPL.

Upgrades didn't work very well until 5.0.5 came out.

Obviously, make at least 2 verified backups of the entire 5.0.4 system 
if you are upgrading the same machine rather than moving to a new one. 
Use BackupEdge (www.microlite.com) or loneTar (www.lone-tar.com) as they 
do bit-level verifies.

BackupEdge has an interesting option to restore an entire system backup 
using an alternate root - mapping on the fly all the tons of symlinked 
files SCO uses to the new root. This allows you to peruse config files 
and such without disturbing the new OS.

Only a limited number of 'modern' machines can run 5.0.7 - be sure to 
check the approved list at sco.com.

Consider installing VMware or another virtualization paradigm and 
installing 5.0.7 as a guest OS. This allows a much wider choice of machines.

Good luck.

Grab a copy of the "Lone-Tar" backup software. Use that to make a
*complete* backup of your system, and especially survey and review
needs for and configurations of third party software. (The old
Skunkware tools in particular are seriously repackaged for 5.0.7,
primarily into the "gnutools" package, which was a big step up.)

Then rebuild into a virtualization environment on a more modern host
under VMWare. This gets you under much better hardware compatibility
than using an *8 year old* operating system and trying to get drivers
for modern network and storage devices. A modern virtual host will
certainly provide better performance than such an old OS was designed
for, and will ease backup and hardware migrations for such a legacy
OS. VMWare and what's left of SCO do offer support for such
configurations.

And remember, this OS is 8 years old: you should be using it only for
legacy compatibility, not ongoing development work.
