I have done migrations from AIX to Linux and from Windows to Linux, and
the nix to Linux migrations are quite easy. The biggest issue is that
your backup method might need to be modified or rescripted to run
correctly. Otherwise, moving from one nix server to another is mostly
installing Universe properly. The application generally migrates easily
with a uvbackup on the old system and a uvrestore on the new system
(most easily done with UniAdmin tools).
Why don't you setup a linux box on a 5 user UV development box and try
the migration.
Let me know if you run into problems.
The other point to watch out for is endianness.
Basically, if you backup your AIX system using uvbackup, then use
uvrestore on linux, everything should be hunky-dory. If you use global
catalogs then you'll need to recatalog, and then everything should "just
run", famous last words ...
If you copy your accounts using cp, or rsync, or whatever at the nix
level, then you'll probably need fnuxi. I'm guessing you're talking
linux on Intel (big-endian), while AIX is probably little-endian. So all
the binary info in the datafiles will be the wrong way round, which is
why you'll need fnuxi to fix it. Once you've done that, and again
recatalog'd any global catalog stuff, again it should "just work" ...
Admittedly I've been running all on Intel, but I've had no trouble
copying accounts between SCO Unix, linux, and Windows. It works fine
with minimal hassle as long as you are aware of the pitfalls.
Cheers,
Wol
