Assuming your starting this process at time T and the current lease time you
have configured for all the clients to be X hrs

Start
1. Change the configured lease time for the 10.10.x.x scope to about an
hour, say Y hrs
2. Wait until T + Xhrs
3. Create the new scope 10.100.x.x. and add/update all the related options
including lease time as X hrs
4. Let all your employees, etc know that your network may have problems for
the next Y hrs.
5. Disable the 10.10.x.x scope
6. Enable the 10.100.x.x scope
End

Thx, Ravi
