OS migration - Heterogeneous system copy

[jamal_asi]

I know it is possible to perform an export on the source system and after the export is completed, the entire export directory is copied from the source system. After that, the source system is shutdown and the target system is started where the export directory is restored and the installation and import are performed. Here both the source system and the target system have the same hostname and the same SID name.

If Migration Monitor is used where both the soure system and the target system are up for the export/import process to run simultaneously, then the hostnames/SIDs can not be same which means that the hostname and the SID on the source system must be different than the hostname and the SID on the target system.

Was anybody able to perform a parallel export/import using the Migration Monitor where the hostname and SID are the same on both the source and target systems?

ALL suggestions, comments and advises are appreciated!

Hi Jamal,

You can perform parallel export/import using migration monitor using the same hostname and SID.

What you need to do is  isolate the target system by not adding the hostname into the DNS server.

Doing this, target system address is not published on the network and hence no issues with duplicate hostnames.

Hope this helps

Hi Jamal,

  It is possible as said by Deepak.

Only consideration that you should take into account is that since hostname are same in both source and target. Try to ensure that you use a different IP Address in the host file and as well as DNS SERVER SHOULDNT be updated with the target system details. Once the export is completed, shutdown the source system and enable the details in the DNS server of the target system.

This will work.. Recently we performed the same work around in our landscape for our migrations.

Thanks and Regards,
