Managing the pools behind a GTM

Hello All,

 

I am using GTM to send end users to the nearest available client VPN gateways globlly. The setup is as follows:

 

I have a wide-ip setup on the gtm by the name VPN.abc.com The wide ip has a pool attached to it by the name VPN_Pool The VPN_Pool has 6 resouces inside it bearing public ip's This existing setup works fine, however recently i have upgraded the existing VPN devices globally to a new hardware and so to test the new setup globally via the gtm i now have:

 

Another wide ip on the GTM with the name VPN.def.com This wide ip has a pool attached to it by the name new_vpn_pool The new_vpn_pool has 6 resources inside it bearing new public ip,s

 

For the migration to the new_vpn_pool i want to know if i can replace the original VPN_Pool with new_vpn_pool so that the ned users can continue accessing the vpn via the original wide ip vpn.abc.com

 

Any help would be greatly appreciated. Thanks
