We've been using Ispconfig for several years. We've just migrated one server from v2 over to v3 and had good results with our testing. We had the test server running on a x.x.x.235 IP and moved it to the old server IP of x.x.x.228. Now we're having resolving issues with several of our sites. When I use dig, it points back to x.x.x.235 instead of the .228 IP. I've changed the IP on the server, changed it in Ispconfig, changed them in the DNS records files but without any change. Any thoughts?
