sancopy plus change of ipaddress
Hello,
We have started the SAN Copy by fibre channel on three LUNs between two CX4-120.
We plan to move one Clariion to a remote location and continue the replication by iSCSI.
The IP address of the storage processors will change and also the replication protocol will change from FC to iSCSI.
Is it possible to keep the incremental copy and continue the replication with only changes?
What would be the steps to do that?
Thanks guys and I hope you have some ideas!! =)

Just to let you people know. We completed the operation today, everything worked as expected:
Last week
1. Setup incremental replication by FC using SAN Copy.
2. Every night a script synced both copies.
Today
1. Removed the target Clariion from multi-domain management interface in Navisphere Mgr.
2. Changed the IP Address of the target Clariion to the new IP for the remote location. (Following the procedure on from Clariion Procedure Generator)
3. Physically transferred the Clariion to the remote location.
4. Turned on the Clarrion on the remote location. Added him backup to multi-domain management.
5. Added a disk-array iSCSI connection between both Clariions.
6. San Copy->Update Connections...
7. Added the iSCSI connection to the Storage Group.
8. Removed the FC connections from the Storage Group.
9. Select "Start..." SAN Copy to sync both LUNs.
The SAN Copy session copied the blocks that changed incrementally since the last FC inc session.
Cheers

Hey, thanks for the update Alfredo. I saw your original post and was curious if that would work as I had no clue. Glad that it worked out for, nice job!
