i have to migrate a iscsi svm (luns are for exchange server) from cluster A to Cluster B (new hardware).
As preparation i have done following:
-I have snapmirrored all volumes from A to B.
-I have copied all igroups from A to B.
-On B I have mapped the luns to igroups with the same LUN IDs as these are used for lun mapping in A.
-On the Day of final migration , i will take the iscsi Lif IPs from A to B.
-On the Day of Migration, the exchange admin will shutdown his exchange server. Then I will do my final storage tasks and then he will start his exchange server and he expects to everything works fine.
My questions are:
-Are my preparation ok?
-The iscsi server on B has another target-name than the iscsi server in A. Shoud i rename the B target-name to the name of the target-name in A?
-A colleague told to me, the vols in B have to have the same uuid as in A. Is that right?
