Patching on release day

Hi folks, I run a private server and I was wondering if anyone knows how release-day-patching will work for us. Funcom said they’re bringing down official servers on monday night for wiping and patching to release-patch. Will we be able to do the same for our own servers, so that we are ready for launch on may 8th? Or do we have to wait until 13:00 CET on may 8th to patch our servers?
