I have a WordPress Multisite installation (with sub-domains). Plus I use WordPress MU Domain Mapping to have separate domain name for each subsite.
Now, I want to migrate all this to a new server (NO change in domain name). The potential problem I see is with domain mapping plugin. I cannot set the same domain name on the old server as well as new server at the same time. I think it will corrupt routing tables etc. Am I right? Do I have to use temporary domain names?
If you have done something like this please do share some suggestion to do this in the best possible way.
