These are the steps for GUID Refresh
1. change the nqserver for FMW GUID update set it to YES
>bicfg
vi NQSConfig.INI
FMW_UPDATE_ROLE_AND_USER_REF_GUIDS = YES;
2. Change the instanceconfig.xml for GUID update on presentation side
> pscfg
vi instanceconfig.xml
<UpdateAccountGUIDs>UpdateAndExit</UpdateAccountGUIDs>
3.stopall opmn components
> bi
./op* status
./op* stopall
4.start the opmn servers
> ./op status
> ./op* startall
5.Wait for sometime as the GUID Refresh would be started in the backgroud,
you can verify this by tailing the upgrade log
>pslog
tail
6. After sometime the presentation services would be down when the GUID Refresh is complete
7. >bi
./op* status
to see if the ps is down
8. Revert back the changes in Biserver config and ps server config
comment the guid part in ps and FMW_UPDATE_ROLE_AND_USER_REF_GUIDS = NO;
<!-- <UpdateAccountGUIDs>UpdateAndExit</UpdateAccountGUIDs> -->
9. >bi
./op* startproc ias-component=coreapplication_obips1
./op* status
