DP 9.07 offered new feature supporting multiple interfaces to same store. It helps resolving a long ongoing limitation with replication to FC configured devices. So far a store could be configured in DP with either IP or FC identifier. Thus in replication jobs with FC device target underlaying catalyst copy operation couldn't be started properly. It works only over IP and we simply didn't have information about target IP address.
Starting with 9.07 it's recommended to use IP address or FQDN of StoreOnce appliance when configuring device to take advantage of the multi-interface feature. Then FC option can be selected for each gateway separately, and it could failover to IP. Unchecking either of the options can make it pure IP or pure FC device.
Question remains what happens with preexisting devices:
1. IP configured device - options "Use FC" and "Fallback to IP" are available in gateway settings and can be manually enabled.
2. FC configured device remain unchanged during upgrade to 9.07, it remains pure FC device. Options "Use FC" and "Fallback to IP" are not available in gateway properties and it still cannot be used as replication targets. However it can be transformed to multi-interface device with following steps:
a) this is original CoFC configured device:
NAME "b4500CoFC"
DESCRIPTION ""
POLICY BackupToDisk
TYPE ObjectStore
REPOSITORY
"038ea8c0_57a8251d_174c_0005"
DIRECTORY
"\\COFC-CZ25200KYF01\CoFCStore" "" ""

b) creating IP configured device using same store:
NAME "b4500CoIP"
DESCRIPTION ""
POLICY BackupToDisk
TYPE ObjectStore
DIRECTORY
"\\192.168.142.14\CoFCStore" "" ""
MGMTCONSOLEURL ""
c) using new "omnimm -merge_library" command to merge both
C:\Users\Administrator>omnimm -merge_library b4500CoFC b4500CoIP
Successfully merged library b4500CoFC with library b4500CoIP.
This leaves only the target b4500CoIP with all gateways and media of source library moved to target library. And as gateway names remain the same there are no changes needed in backup/copy specifications.
