Storage Migration Service - Destination Proxy Wasn't found

[CathiMT]

Under the "Transfer Data" when "validating" source and destination, I am getting a warning that the destination proxy wasn't found.  I installed the Storage Migration Proxy on the 2019 destination servers and rebooted them as well as my orchestration server, but it still fails saying destination proxy wasn't found.  Is there some kind of trick to get this to work?

I found the answer to this issue:

1) install Storage Migration Service Proxy on destination servers (in my case they were 2019)

2) Run windows updates and reboot

3) Reboot WAC and destination servers 

4) Wait for WAC orchestration server to pick up the update - i waited a couple hours
