So my nextcloud server exploded and like a dumb dumb my database & config backups were out of date.
I still have access to the drives for a while and am copying over all the files to a new (managed) nextcloud server.
What will happen if I change the IP in the DNS for the domain to the new server?
E.g. cloud.domain.com
points to 1.2.3.4 old server which no longer works, so I change this to 5.6.7.8 - the new server.
The files are the same (or content of the files at least, possibly not the mtime), but none of the user accounts can be transferred. The SSL certs aren’t the same either of course.
95% of our 150 user accounts are basically read-only accounts, they have a quota of 0B and are given read access to some files. The other 5% are our team accounts that have read+write access to all the same files on the admin user account, and generally don’t store their own files.
What will happen in the Desktop client if I changed the DNS?
I imagine first an authentication (and possibly SSL) error, but if that is resolved with new credentials, how will the clients behave?
Most of them have complex selective sync options, and some will likely have new files added since the old server went kaput. But for the most part, everyone already has the majority of files downloaded.
There’s about 2.7 TB of data.
Would it be better to just start from scratch and ask everyone to delete their connection and use a new one on a different domain?
