F5 DNS additional zone

Perhaps an obvious question. I have a sync group hosting a gslb.zoneA.org. I want to build out new environments for gslb.zoneB.org and other subdomains. This seems just as simple as adding a new wideip and letting it update the zonerunner list. Then adding the zone list entry manually.

Are there any gotchas with regard to hosting multiple domains/zones on a single GSLB environment?

Thanks!
