What’s the actual effect of the ALTERNATE_DOMAINS list with an instance? Does is simply give you an alternative access URL while everything is still run on the LOCAL_DOMAIN internally? Or does it have any kind of deep interaction where you can add @firstname.lastname@example.org from other instances and have it treated identically to the original?
The scenario is that the .org variant of my main domain became available recently and I grabbed it. I’d ideally like to migrate everything over so that’s the primary reference point for everything. My old domain will never be unavailable though.
Currently I’ve added the .org as an alternate domain and it’s working as expected, available via the new URL but still referring to everything as the old domain in links etc. However, if at this point I were to swap the local and alternate domains in the config, what should happen?
