Hi MW,

 

 

If you have a dedicated link (untrunked) between the two units which you use only for network failover, you could conceivably bring that up, set the new unit to standby and then bring up the other links/vlans without any downtime. You could try to do this with no downtime/effect on live traffic, but I would suggest scheduling a maintenance window anyhow.

 

 

If there is no official support for HA in the virtual edition, I don't think it would be a valid test.
