Hey Alexander,

 

 

As I understand your question, I don't believe it is possible to accomplish this. It has, however, been quite some time since I worked on the GTM so I could very well be missing some magic that might make this possible.

 

 

While it isn't an ideal solution the only thought that comes to mind for me is to configure the old WIPs on the new GTM and use an iRule to log requests to them. Either the DNS_REQUEST or DNS_RESPOND events would allow you to log these events for the WIPs and even record other information in the logs to help determine if the requests arriving are valid or invalid.

After some time you should get an idea of which of the old WIPs are no longer required and which are. It isn't an elegant solution by any stretch of the imagination, but I'm a loss for any other.
