Best way to migrate Citirx ADC & Gateway to F5 Solutions

Build out the Citrix Gateway on F5 using f5.citrix_vdi.v2.4.5 iApp. The iApp is very simple. It will ask you for a DNS name for using this, so you should just use a test DNS name. Once iApp is configured, test DNS entry is in place, and firewall rules are configured, test it for a long time.

After VERY thorough testing, reconfigure iApp to use production DNS name, and cutover your production DNS to point to the F5 gateway VIP instead of the existing Citrix gateway.
