Move imported log statistics to a different host name

I’ve been using piwik for a couple weeks now and it’s perfect, it parses log files AND tracks users with JavaScript so it’s ideal for my uses.

The problem I’m having right now is that when I was first parsing log files they didn’t have the host name on the record so it went in as the default host name for the siteid I provided. I’ve since changed things and now the logs are properly putting in the host name the users are visiting but now my stats are being split for downloads between the old locations and the new ones.

Is there any way to merge that info? Can I simply replace in the piwik_log_action table under the name field?
