Just to throw in another $0.03 (adjusted for inflation),  Generally most successful migrations I've seen from AFP servers to CIFS servers (specifically Celerra) have gone pretty much exactly like you say.  In the olden days "ditto" would have been the preferred utility (since it was Resource-Fork aware) but the modern Apple "cp" generally does everything that needs to be done.  Besides the fact that AFP/HFS+ supports characters not supported in CIFS/Windows (and you've found a good solution for that), Resource Fork handling is probably the biggest potential gotcha.  Like Rainer said, fresh 10.6 clients, 10.5 and below or upgraded 10.6 clients, and systems using Thursby's Dave or ADmitMac CIFS clients all handle Resource Forks in different ways, and if you have a mixture of these clients in your environment things might get a little bit messy.  But otherwise, you shouldn't have any other general problems.  If you have 10.6 clients, make sure you're running the latest versions of OS X (10.6.3) and Celerra code (at least 5.6.47 or later).  Both updates contain some fairly critical bugfixes for CIFS/OS X compatibility.   Be careful if your source AFP volume and destination CIFS volume have the same name, and you plan to keep both volumes mounted for a while.  OS X also still has a peculiar bug that can really confuse applications (particularly MS Office) if two volumes are mounted with the same name at the same time.  With certain types of filesystem calls, OS X will accidentally send I/O to the FIRST volume with a particular name, even if the application intended the I/O to go to the SECOND volume with that name.  This has tripped up at least a few Mac migratees - the workaround in that case is just to unmount the AFP volume, or make sure they're mounted/exported using different names.
Hi everyone,  We are looking to move data hosted on 3x Apple Xserve's (Leopard 10.5) to a new Celerra (running code 5.6.47-11).  I assume other EMC customers have moved from a similar environment and am interested in knowing the method you used to copy data from Apple->Celerra, challenges encountered, or any suggestions you may have in general.  At the moment we are testing data copy via the following:  - Mount AFP (Xserve) user volume and CIFS (Celerra) user volume on a Snow Leopard workstation - In Terminal, we use cp -Rvp /Volumes/ /Volumes/  to copy data from user's AFP volume to CIFS volume  ... this seems to work fine, preserving modification dates, resource forks, etc.  The one thing we've noticed so far is there are some file/foldername characters that AFP is fine with however not so with CIFS.  We are using a tool (Namecleaner X) to cleanup file/foldernames so they are CIFS compliant.  Any feedback would be appreciated.  Many thanks, Darren
