Hi!  
On target node i see the following messages in log:  
Oct 14 12:20:17 neon ovs-vsctl: ovs|00001|vsctl|INFO|Called as ovs-vsctl --timeout=5 – --if-exists del-port  
Oct 14 12:20:17 neon ovs-vsctl: ovs|00002|vsctl|ERR|‘del-port’ command requires at least 1 arguments  
Consequently ‘premigrate’ script didn’t start and migration fails.  
Maybee this is a bug in 4.14?
