AIX v4.3.3 vs. 5.1 & 5.2 3

IS-IT--Management
We went with a clean install on a new machine, so I cannot offer you info much on a migration installation.
Not too many problems, the main ones I can remember where the IBM C and C++ compilers we had would not run on 5.1 so we had to get a never version.
Version 5.2 seems to be only 64bit, so it won't install on an older 32bit machine like a 43P.

Migration Install from AIX 4.3.3 to AIX 5.1 ML 3
(also works for 5.2 NO ML ) I was going to 5.1 but found the end of service date for 5.1 was next year. So I am going to 5.2 instead. I hope this helps.
Migration Install from AIX 4.3.3 to AIX 5.1 ML 3 ( and AIX 5.2 ML 0 )
Pre Migration
The migration will not update the 4.3.3 documentation. You must first un- install the 4.3.3 doc, do the migration, then install the 5.1 doc.
bos.html.en_US.cmds.cmds1
bos.html.en_US.cmds.cmds2

bos.html.en_US.files.files_ref
bos.msg.En_US.sysmgt.nim.master_gui
bos.msg.en_US.sysmgt.nim.master_gui
Uninstall the aix 4.3.3 doc
back up your motd, the migration replaces it with the standard "welcome to aix"
run lppchk -v and fix any problems first
AIX requires certain user and group definitions to remain unchanged.
root:!:0:0::/:/bin/ksh
deamon:!:1:1::/etc:
bin:!:2:2::/bin:
sys:!:3:3::/usr/sys:
adm:!:4:4::/var/adm:
uucp:!:5:5::/usr/lib/uucp:
guest:!:100:100::/home/guest:
nobody:!:4294967294:4294967294::/:
Verify that your /etc/passwd has entries matching the following:
It is important to verify that the preceding entries exist and match exactly. Also, verify that no other user has UIDs that duplicate the preceding. The UID is the third colon-separated entry, the first number.
system:!:0:root
staff:!:1:
bin:!:2:root,bin
sys:!:3:root,bin,sys
adm:!:4:bin,adm
uucp:!:5:uucp
mail:!:6:

cron:!:8:root
printq:!:9:
audit:!:10:root
ecs:!:28:
nobody:!:4294967294:nobody
usr:!:100:guest
Verify that your /etc/group file has entries matching the following:
xlC.rte must be at 5.0.2.0 or better ( or apply IY17981 ) p 321
run usrck -n ALL ( make sure all errors are a known part of the environment)
run grpck -n ALL ( make sure all errors are a known part of the environment )
backup any cron or at allow or deny files ( /usr/adm/cron.deny )
if you have TCB then run tcbck -n ALL and correct any errors.
space requirements /tmp 15 MB free, / 10 MB free, 80 MB of unallocated PP's on rootvg disks
break all mirrors of the rootvg. You should have no mirrored copies of rootvg during migration
make sure you change your bootlist to reflect you have only one disk ( bootlist -m normal hdisk0 )
make sure the disk in your bootlist is also the disk you booted from
ls -l /dev/ipldevice /dev/rhdiskY ( where Y is the hdisk number listed in the bootlist )
if the numbers in the 6th column dont match, fix this before going on
make sure /tmp has no bad file names. ( all files should be alphanumeric )
make sure all logical volumes in all vg's are synced
check perl. The migration is going to install perl 5.8.0 in /usr/opt/perl5/lib/5.8.0 and change the link /usr/bin/perl to point to this
I had to copy the MIME dir from my old perl to the new one to keep mailibm working
Post Migration
verify LPP with lppchk -v
Verify current OS and Maintenance level with oslevel -r
Check for previous level file sets still installed on the system
lslpp -l | grep 4.3 | grep COMMITTED
some third party software may need to be removed by other support groups
remove any old 4.3.3 file sets
perfagent.html.en_US.usergd 4.3.3.0 must be removed for example
check for broken file sets
lslpp -l | grep BROKEN
correct any problems
make sure instfix sees your oslevel and ML level ( instfix -ik 5100-03_AIX_ML) NOTE: 5.2 this does not work... there is no ML for 5.2 yet
I:bos.html.en_US.cmds.cmds1 5.1.0.0
I:bos.html.en_US.cmds.cmds2 5.1.0.0
I:bos.html.en_US.cmds.cmds3 5.1.0.0
I:bos.html.en_US.cmds.cmds4 5.1.0.0
I:bos.html.en_US.cmds.cmds5 5.1.0.0
I:bos.html.en_US.cmds.cmds6 5.1.0.0
I:bos.html.en_US.files.files_ref 5.1.0.0
Install the AIX 5.1 Doc
* Note: when doing installs, there is a new field that asks if you accept the license. Its default is "NO". If you install this way, you will not get an error, but the software will not be available to you. I installed the man pages this way and the man command replied "there is not an entry for ls " To correct this, I had to reinstall with the license set to "YES". Once it did that, all was fine.
run lppchk -vm3 to see what file sets are not compatible with AIX 5.1
If you have any file sets that show up with lppchk -vm3 then you will need to remove them or update them. I had to remove
perfagent.html.en_US.usergd
and I had to call DSMBR to remove some TSM code that was NOT compatible with 5.1.
remove the /etc/hosts.equiv the migration will create for you
check /etc/security/user default stanza for repeat information. It does not delete the default info, but adds a complete new set of attributes underneath the old ones. The new attributes are completely wrong from a security standpoint, so you need to delete this. repeated info starts with xxxx to the end of the stanza
remove IMNSearch file sets ( 9 of them )
check /u this link has been reset to point to /home. I had to set it back to the auto mount link.
remove bos.net.snapp ( System Networking Analysis and Performance Pilot )
comment out daytime and time which were added to inetd.conf during the migration
comment out wsmserver from inetd.conf
comment out cmsd, ttdbserver, and dtspc from inetd.conf
restart xntpd if you were using it. un comment in /etc/rc.tcpip
comment out hostmibd in /etc/rc.tcpip
comment out the httpdlite entry in /etc/inittab that was added during the migration
comment out the ctrmc entry in /etc/inittab
comment out the itess entry in /etc/inittab
change group on /etc/passwd and /etc/opasswd to security ( it will be system after the migration this is wrong )
change permission's on /etc/passwd and /etc/opasswd to 644 ( it will be 664 after the migration this is wrong )
Notes :
The migration creates a group snapp id=12 admin=true users= registry=files
The migration creates a new group "lp" GID 11 ( root and ID lp [see below ] need to be in this group )

You have to make sure first, that your applications will run on the new version of AIX that you are migrating to. And if they will not, you have to aquire the upgrade software for them.
You'll have to go to the application vendors to find out if they'll run on the version of aix you want to upgrad to, not to IBM.
Make sure you also tell the vendors you are going to be upgrading aix as well as their software and get their recomendations for how to migrate their applications.
some of the most destructive problems can be prevented by just doing some extra planning.
