Yes we have a multisite network set up with multiple domains which we need to keep, serveral sites live on this network! One of those domains I have set up as test.domain.com for staging purposes. Now the sites is almost finished and I need to move if from one domain (test.domain.com) to another (www.maindomain.com). The https://www.maindomain.com is already apart of the network. Thanks in advance for your input!
