K15496: Migrating new BIG-IP platforms to an existing device group

F5 Support answered back which they are pretty quick on F5 Support Rocks!!!. Don't think there are any other options which Guru's here can suggest.

1. when I add new vCMP guest into LTM cluster, what additional steps I need to perform in GTM?

2. Either you upgrade the GTM to version 13.1.0.3, which will allow you to have a "Redundant Big-IP system" with 4 units in it or you create two traffic groups on the LTMs and make one member of each cluster as active state and then create a second redundant system on the Big-IP DNS to add the new LTM pair to it.

    

3. What precaution I need to have before removing "LTM-XYZ1/2" IP address from GTM Server object ? Will I lose all the virtual server objects earlier discovered by GTM from mentioned LTM cluster by removing them from configuration?

    

4. Assuming you want to keep the GTM on version 12, when you remove the "XYZ" LTMs, all virtual servers associated with it will be removed.

    

5. Is there any way to modify existing server object "LTM-XYZ1/2" to "LTM-PQR1/2" without impacting existing Wide-IP configuration?

    

6. Assuming you want to keep the GTM on version 12, if you create two traffic groups on the LTMs, you will need to manually add all elements from the new clusters on the current pools before removing the old pair, othewise all pools will be empty when you remove the older pair from it.
