vsx reconfigure for non-dmi gateways

[Maller]

Hi all

I'm preparing the upgrade process for a non-dmi gateways , I'm  forced to do a clean install upgrade and then reconfigure. 

As my understanding  the steps must be the following

1-  clean install 

2-  configure IP address on physical interface to set up SIC with management

3-  If SIC is established ok ,  execute vsx_util reconfigure  from management

During step 3 , vsx config transferred to the gw will create a wrp interface and it will move management IP address from physical to this logical interface , is that correct?

Is there any documentacion about this procedure? I've been looking for some official documentation about it , but I don't have found anything.

thanks
