Dear Experts,

We deployed an EBS 2008 system a fair few years ago.  Had a few problems with it along the way and now its time to migrate it off.

MS dropped development of EBS quickly and we took advantage of the "make it right kit" that they offered.  I have just run through this procedure and the DC, exchange and ISA server are all now separate products.

As per the pre-defined, default configuration of ISA in this environment, it has rules for publishing the OWA site amongst others.  It also  hosts the exchange edge transport services.

I'm planning to migrate off to new hardware and would be keen to see the system - as it stands - running without ISA.  

So I would envisage that it might involve the following:

- remove exchange services from the ISA box
- remove the edge subscription from exchange box and create new send connectors
- remove the ISA box
- create rules in the new hardware firewall for smtp delivery to the exchange box, https etc

Would this sound broadly feasible?  I really want ISA out of the picture with the system as it stands now.  I know it would be easier to migrate off and just not include the ISA in that process but I have a use for the ISA hardware prior to the planned migration.  Also, as a priority, I have been tasked with setting up several site-site VPN tunnels with the hardware firewalls that are being deployed and I KNOW that ISA is going to be a problem.

Thanks
