Adding new rSeries Tenant to existing Device Group

We are refreshing our iSeries with rSeries hardware.  I have deployed the new Tenant for LTM and associated the proper VLANs and I see them in the new LTM but they are all in the Common Partition.  On the existing LTM's the VLANS are in their respective partitions.  I have case open with support and they provided guidance on adding the new device to the group to get the configuration synced.  

Can I get any suggestions from anyone that has already gone through this exercise?  I have a change request in for tonight to add this device to the group and I am concerned with the process.

Thanks,

Joe
