When changing lease time in a dhcp server, does that affect current leases or just new leases? Is there any documentation on this?

I believe the new lease time for DHCP Leases only comes into effect when the current old lease expires. For example you had 7 days set previously and the new one is 3 days, once the clients with a DHCP Address lease for 7 days is up then the 3 day lease time will take effect after their 7 days lease is up.


Hopefully the below will help:

it will only affect new leases and renewals...but a dhcp client will start asking for a renewal when it reaches the halfway point of the lease...for example if you have an 8 day lease, clients will attempt to renew at 4 days...and they will get the new lease time...
