Are you saying the following?
https://www-304.ibm.com/support/docview.wss?rs=0&uid=swg21446135#830XAlter the OnDemand database for use with
V8.4.1 and later by running the following commands on your library server. These commands must be run as the OnDemand instance owner specified in the OnDemand Configurator on Windows or the ars.ini on all other platforms.
1. Mandatory. Alter the OnDemand database for V8.4.1 and later:
arsdb -I instance_name -uv
arsdb -I instance_name -mv
2. Mandatory if you have Report Distribution installed. Run the following commands:
arsdb -I instance_name -uRv
arsdb -I instance_name -mRv
3. Optional, but recommended. Update the System Log application group for the longer 2000 character Message Text. If not performed SQL truncation warnings may be issued for certain System Log messages.
arssyscr -I instance_name -l
arstblsp -I instance_name -a 1 -g "System Log"
4. Optional. Create the System Load Application Group. Creating this application group will impact loading performance because a new row is inserted for every load.
arssyscr -I instance_name -a
The other thing I found is 32bit/64bit issue(as 2008 OS is 64bit)
Migrating DB2 32-bit servers to 64-bit systems (Windows)
On the Windows operating systems, there are two ways to migrate your DB2® UDB Version 8 or DB2 Version 9.1 32-bit server to a DB2 Version 9.5 64-bit server.
0. Migrate your existing DB2 32-bit server to DB2 Version 9.5 32-bit server, and then upgrade to DB2 Version 9.5 64-bit server.
1. Migrate to a new computer where DB2 Version 9.5 64-bit database product is installed.
Chosen the second option(where OS is 200864 bit, and DB2 9.7 is installed).
In this case, maybe DB2 9.7 install work is not needed on serverA. Since DB2 8.1 FP8 is upgradable to DB2 9.7 version. So, taking an offline backup on serverA DB2 8.1 FP8 version database should be OK to restore in DB2 9.7 version.
What do you think now?0. perform DB2 pre-req checks for upgrade to 9.7 from DB2 8.1 on serverA (there are tons of steps involved to check).
1. Install DB2 9.7 on serverB.
2. Backup DB2 8.1 database offline on serverA.
3. Install CMOD 8.5 (server, Admin client, windows client and configure DB, place the same path structure and userid/group). Verify CMOD install by logging on to both clients.(on serverB)
4. Run the two manadator and two optional commands
arsdb -I instance_name -uv
arsdb -I instance_name -mv
arsdb -I instance_name -uRv
arsdb -I instance_name -mRv
Optional, but recommended.
arssyscr -I instance_name -l
arstblsp -I instance_name -a 1 -g "System Log"
arssyscr -I instance_name -a
5. Move DB2 8.1 backup database from serverA to serverB.
6. Restore DB 8.1 FP8 from step 5 on serverB , verify, post process.
From this IBM document link for DB migration
http://publib.boulder.ibm.com/infocenter/db2luw/v9r5/index.jsp?topic=/com.ibm.db2.luw.qb.migration.doc/doc/t0011000.htmlMigrating to a new DB2 serverIf you want to migrate to a new DB2® Version 9.5 server, you need to recreate your instances and then restore your DB2 Version 9.1 or DB2 UDB Version 8 databases from a database backup. After restoring the database backup, the RESTORE DATABASE command automatically runs the MIGRATE DATABASE command.
I am not worrying for 32 bit/64 bit(do I need to?)7. Install WAS 7.0, WAS updater, Apply fixpacks (on serverB)
8. Deploy ODWEK 8.5 (on serverB), verify.
11. Apply DB Fixpacks on serverB.
12. Install configure CSSAP or ICC4SAP.(on serverB)
13. Start services of all and verify.
