SD-WAN - Basic Configuration

[SecurityPlus]

We setup a FortiWiFi 60D about 4 years ago using WAN1 only. We are now on FortiOS 5.6.5. The WAN1 internet connection is a very slow DSL connection. Due to the extreme slowness and occasional outages, the need for internet connection redundancy became necessary. One of the most critical usages of the internet connection is to stream video to an off-site server via the WAN from one particular computer. We recently added a much faster connection to the WAN2 interface. We setup a SD-WAN to use these two WAN connections. We configured the   Two questions: 1. The SD-WAN setup instructions say to set up the faster internet connection to WAN1 and the slower connection to use WAN2. In our case the slow static IP address connection was already set up on WAN1 and the newly added static IP address connection was naturally added to WAN2. Does it matter if the slow connection is on WAN1 and the fast connection is on WAN2?   2. Under most circumstances we wish to primarily use the much faster WAN2 connection, at least as it pertains to the video streaming. If the two WAN connections were more similar in speed, a 50/50 mix of WAN1 and WAN2 might be useful. If the much faster WAN2 connection fails we would obviously like traffic to use the WAN1 connection. Based on these factors what is the best way to use this SD-WAN connection?   Thanks in advance.

Any feedback concerning the 2 questions above? Even if not a complete answer any responses would be appreciated.

For question 1,

It is ok , if slow connection is on WAN1 and the fast connection is on WAN2.

question 2.

You can setup SD-WAN to force most traffic go to fast link.
