These options for the ctmigra command-line utility suppress all output (--quiet or -q) or select the information to be sent to stdout (--verbose=LEVEL or -v). The --verbose parameter is a bitmask which can combine the following values:
1 - show message about final result
2 - show percentage progress
4 - show time spent in migration phases (read, write, finalize)
For example, to display everything, use --verbose=7, which is 1+2+4. If not specified, the --verbose level is 3 (1+2).
The --quiet option is identical to --verbose=0.
