Mayur, Find the below answer based on my experience.

 

I am planning for upgrade all devices to 14.x version from 11.x

==> Will personally not recommend you to directly Jump version from 11.x to 14.x. Lot of feature has changed to GTM. It may not allow you to reload the configuration. Check with F5 Support Engineer before taking any steps.

 

Query:-1 ==> Take out DNS statics for listeners 10.10.10.2, If require then configure listeners to other GTM and then upgrade. One more solution is to break SYNC group[Just change the name of SYNC Group] and upgrade based on the requirement. You will face DNS[listeners - 10.10.10.2] issue only during GTM reboot time.

 

Query:-2: As per F5 recommendation big3d version should be same in all F5 products.

 

Hope this will help. If still any question let us know.
