Overwrite Configuration Sync Option in v11

I tried this in my VE 11.4.1 environment.

in GUI, you can "overwrite" newer configuration from an older version.

BUT there is no "overwrite" in tmsh.. there is no "overwrite" option in "run /cm config-sync to-group XXX" command.

the monitor session did show below message: looks like it is in a "force-mode".

run /cm sniff-updates

Listening for commit_id_update on -i internal:h port 6699 (^C to exit)

[19:56:43] bigipA2.f5demo.com (v11.4.1) -> ltm-lab-grp01: UPDATE CID 108.0 (bigipA1.f5demo.com) at 19:46:04 FORCE_SYNC

However, Both units still not in sync. I ends up using the GUI and check the "over-write" feature to force the older configuration sync to the group.

From the SOL114856: Ver 11.2.x and above, you should be able to "over-write" configuration from older version.BUT it seems not working?!?! see link: http://support.f5.com/kb/en-us/solutions/public/14000/800/sol14856.html
