How to perform a mksysb to mksysb migration
Answer
Problem: Customer needs to migrate a mksysb
Action Taken: The customer has a mksysb image of a 7025-F80 running AIX 5200-04, and wants to install that image to a new 9110-51A Power5 system.
The minimum AIX requirements for the 9110-51A are:
* AIX 5L for POWER V5.2 with the 5200-08 Technology Level (APAR
IY77270), or later
* AIX 5L for POWER V5.3 with the 5300-04 Technology Level (APAR
IY77273), or later
Customer decides to just perform a mksysb to mksysb migration of the 5200-04 image to 5300-09.
To perform a mksysb to mksysb migration by using these resources:
spot: 5309spot
lpp_source: 5309lpp_source
orig mksysb: 5204_mksysb
new mksysb dir: /export/mksysb/
new mksysb NIM resource: 5309_mksysb
new mksysb filename: new_mksysbfile
temp vg to use: rootvg

Command line:

Customer received this error:
Initializing the NIM master.
0505-205 nimadm: The level of bos.alt_disk_install.rte installed in SPOT
53spot (5.3.9.0) does not match the NIM master's level (6.1.1.1).
Cleaning up alt_disk_migration on the NIM master.
Install the matching AIX 6.1.1.1 bos.alt_disk_install.rte fileset to the 53spot
# nimadm -T 5204_mksysb -O /export/mksysb/new_mksysbfile -s 5309spot -l 5309lpp_source -j rootvg -Y -N 5309_mksysb

Install the matching AIX 6.1.1.1 bos.alt_disk_install.rte fileset to the 53spot
# smitty nim_inst_all
>> Target: 5309spot
>> Source: 61lpp_source
>> Software: bos.alt_disk_install.rte
Since 5.3.9.0 has a later build date than 6.1.1.1, we cannot install it over the 5.3.9.0 version. We must remove the 5.3.9.0 version, and re-install the 6.1.1.1 version of bos.alt_disk_install.rte
# smitty nim_remove
>> 5309spot
>> Software: bos.alt_disk_install.rte
# smitty nim_inst_all
>> Target: 5309spot
>> Source: 61lpp_source
>> Software: bos.alt_disk_install.rte
The level is still incorrect:
# nimadm -T 5204_mksysb -O /export/mksysb/new_mksysbfile -s 5309spot \
-l 5309lpp_source -j rootvg -Y -N 5309_mksysb
Initializing the NIM master.

Cleaning up alt_disk_migration on the NIM master.
The lpp_source only had the 6.1.1.0 version
# installp -qld . | grep bos.alt_disk_install.rte
bos.alt_disk_install.rte 6.1.1.0 I
We locate the 6.1.1.1 update for bos.alt_disk_install.rte and copy this to the 61lpp_source, and update the .toc file.
Now we update the bos.alt_disk_install.rte to 6.1.1.1:
# smitty nim_inst_latest
>> Target: 5309spot
>> Source: 61lpp_source (which now has hte 6.1.1.1 version of
bos.alt_disk_install.rte)
>> Software: bos.alt_disk_install.rte
Now, we finally have the right version of bos.alt_disk_install.rte
Try the NIMADM again:
# nimadm -T 5204_mksysb -O /export/mksysb/new_mksysbfile -s 5309spot \
-l 5309lpp_source -j rootvg -Y -N 5309_mksysb
The mksysb to mksysb migration is now working.
