Cleanup Stale Sessions - needed?

Hi Radius Gurus

I have a problem with one not-so-typical situation.

First of all, I am running daloradius on top of Freeradius:

[root at radman ~]# radiusd -v
radiusd: FreeRADIUS Version 2.1.7, for host i686-redhat-linux-gnu, built
on Mar 31 2010 at 00:25:31
Copyright (C) 1999-2009 The FreeRADIUS server project and contributors.

PARTICULAR PURPOSE.


I have just update my network topology and therefore I moved some NASes
from one server to another.

When I did this change, obviously I did it without worrying what could
happen to the radiusd. So I simply moved the NASes on new IPs/servers
and restarted the radiusd.

Now I have the users trying to get into the network but they look
"online" to radiusd on the old NASes. In few words the connection is
refused because radiusd thinks that the user is ALREADY online on the
"old NAS" (not true) and it does not permit the user to get into the
network.

So I have this teasing menu option in daloradius which is called
"Cleanup Stale Sessions". I think it does exactly what I need but:

1) I do not want to break the radiusd
2) I do not want to loose my radius logs ("who had that IP that day..")
3) I do not know if this is the right "button" to click

So I am asking you if you have any idea of how to solve this issue and
if I should click that button

Thank you in advance
