Customer needs to migrate the NetScaler gateway environment to an IPv6 based networking environment

Instructions

IPv6 configuration on NetScaler just needs to replace the IPv4 configuration with IPv6 Address. Also take care of the following:
1. Enable IPv6PT feature on NetScaler.
2. SNIP needs proper prefix as part of IPv6 standard.
3. Add appropriate AAAA Record( IPv6 host record) on DNS
4. LDAP test connection cannot work with serverIP configured with IPv6 for now, use server name in config as workaround.
5. For http to https redirection, you need to configure two LB vservers listening to http-80 requests for handling both IPv4 and IPv6 traffic

Also, refer to the below Citrix document for additional info:
