Migrating to Failover

Thanks for the note. I'm moving to two completely new, standalone servers.

So when I fire up a server with a new subnet, it looks like the lease
files are automatically populated with "free" or "backup" entries.
Interestingly, the entire pool has lease entries marked "free". The
second half of the pool has a second lease entry marked "backup". I
guess these second leases take precedence, allowing the secondary
server to use the backup entries?

I'm testing some scenarios now, but can I append my real leases to the
end of this generated file? Or do I need to append them before these
entries are generated?

Thanks,
