This step is only required if home cluster is on 5.0.5.2/5.0.5.3. You can 
ignore this issue, and restart AFM filesets at cache.

Hi,

Sorry for the delay...

At point 3 I'm getting:

# mmafmlocal rm <target path>/.afm/.afmctl
/bin/rm: cannot remove ‘<target path>/.afm/.afmctl’: Operation not 
permitted

afmconfig disable is the same.

Any idea what the issue is?

Thanks,
Rob
