LTM Traffic group failover

I am still having the issue, it appears that one specific traffic group will go "Active" on another LTM but the traffic still seems to be "stuck" to the original active device.  I failed a different traffic group over to another LTM without issue this morning but tried to move the CORESERVICES one last night and the mac/arp entries were still present on the orgiinal F5.

I had a case open with F5 and they stated that I needed to disable the VIPs on the existing LTM after I migrate force it to standby...but since they are in a config sync group that would shut down the VIP's for all LTM's.  I am lost at this point.  I am going to work on moving all traffic off the existing LTM and then rebooting it to see if that clears the issues.

Any  ideas would be appreciated..

Thanks,

Joe
