Changing the DNS scavenging server

I am in the process of demoting one of our old DC's (I have 3 DC's in the domain).  This DC is also set as the scavenging server for the AD integrated DNS zones.  I want to change the server to one of the other ones but I noticed the following when I look at the zone aging properties on each DC.

1.  The zone properties on the DC which is the scavenging server has a Date and Time of 3/17/2011 7:00:00PM which is correct.
2.  The same ad dns zone properties on the DC that I want to set as the new scavenging server has a Date and Time of 11/14/2007 3:00:00 PM on the Zone aging properties.

When I change the setting to the server in step 2. above, is that going to cause me problems based on that old date, or will it reset?

Thanks

That date only indicates that the server could be scavenged after that date, dont worry if the date is old, when you enable scavenging on that server, that time stamp should change.

If unsure, you can set scavenging on both servers before demoting the first server and then disable on the first server, this will not make any visible change, if the scavenging after timestamp has not changed (which will be very strange) you can safely re-enable scavenging on the first server.

Remember that this process only purges records which have not been updated > the sum of the non-refresh and refresh period, if the timestamp in  a record is > that the record will be purged, otherwise it will be retained.

also if the record is deleted the computer can re-register when it is reconnected, restarted or will automatically update it every 24 hours.
