ISPConfig3 -> ISPConfig3 Migration Problem

So the dry run completed on my migration, but when I actually go to do the migration I get a big fun wall of errors. Getting the dry run to work to begin with was an experience, it really doesn't seem to cooperate with servers that require private keys for logon (like newer digitalocean droplets). I ended up having to transfer the key over manually to get it to run at all, and I feel like this error is related to that.
