Transitioning from one URL-server to another

[jonesl1]

Ok, I have a question (not surprising).

We have 2 ASA 5520's that are hooked together in an active/active standby failover mode.   Both using version 8.2.(1).

Currently on thses ASA's, we point our internet requests to a centrally located URL-server (N2H2).   However, recently this N2H2 server has become

obsolete and is going by the wayside.  The new URL-server (Netsweeper) uses websense.   My company has approximately 3000 people in it and

therefore makes it a little difficult to just take the internet down and switch over to the new one with very little testing.  

My question is....is it possible that I can run both and send only a certain subnets internet requests to the new websense URL-server while the remaining

continue using the old?

I'm needing a way to transition over to the new one, but I need to test the functionality of it on the network before implementing it across the board.

Thanks in advance!

No, unfortunately you can only run 1 type of URL server at any given time, therefore, won't be able to run both N2H2 and Websense at the same time.

Here is the configuration guide for your reference:

It would be best to organise for a down time after hours so you can perform the testing.
