The existing SOA and NS records of the zone under the zonerunner will not be overwritten by the above operations. I recommend you to delete the wideip www.wip.domain.com and then delete zone wip.domain.com under zonerunner
Finally, modify the SOA and NS record values of the zone automatically generated by wideip:
modify gtm global-settings general wideip-zone-nameserver gtm2.wip.domain.com.
After the above steps are completed, you can create a wideip www.wip.domain.com, and then observe the SOA and NS records whether change to gtm2.wip.domain.com.

and create a another wideip www.test.com, and under the ZoneRunner zone test.com. 

its NS and SOA will also be gtm2.wip.domain.com.

Tips： low version in GTM, such as V12, wideip create zone default SOA and NS value is F5 hostname
