ted:  I agree with you.  I've done it that way in the past.  However, what I'm going to do is this:  1.     Set up the new switch, virtual fabrics, domain IDs, etc, the whole thing. 2.     Discover the new switches in Connectrix Manager Data Center Edition (v10); wherein the old McData SAN Switches are already discovered.  (We use Connectrix Manager to Zone.) 3.     Map out the target port locations. 4.     "spoof" the target port FCIDs for ONLY the Storage Ports.  It turns out that HP-UX CxTyDz numbers only change when the Storage Port FCID changes.           o     i.e. - if the McData Storage Port FCID was "610413" make the new Brocade Storage Prt "610413". 5.     "Save" the Zoning config for each old fabric from Connectrix Manager. 6.     "Restore" the Zoning config to the NEW Brocade DCX SAN Switch!  (This process should take only 10 minutes or so!)  I'm going to try this today.  thanks for your help.       Stuart
I believe that there is a tool that allows you to "pull" the fabric/active zoneset/zones from the ED-140M and "install" them on the Brocade DCX?  Does anybody know how to do that?   I'm NOT going to put the McData and the Brocade in the same Fabric (i.e. - ISL them), with InterOp Mode, and all that stuff.  I'm just going to shut down the McData, and move the SAN cables; one Fabric at a time.  Does anybody know how to do this?     Stuart
I'm migrating from McData ED-140M to Brocade DCX SAN Switch. How do I "pull" 
zones and install on DCX?
