Hello Wessel:

Currently Kea does not cache any lease information when you use one of
the RDBMs backends for lease storage, so you should be able to simply
insert them.  The only negative effect this would have on a running Kea
is that lease statistics would be inaccurate until Kea is told to
reconfigure or recalculate statistics (see command channel commands) or
Kea is restarted.
