Hi!
I’m preparing to migrate some Discourse instances to new hosting. The plan is to set the old site read-only, take a backup, move that across to the new hosting and restore while updating the DNS settings (on a short TTL). This process is all taken from guides here and around.
I’ve been doing some dry-runs on this, using a /etc/hosts file hack to simulate the DNS update (and with DNS over HTTPS disabled in the browser too). So far so good.
However, despite being careful to close the browser on the ‘source’ site, then only opening it after complete migration on the ‘destination’ site, it forgets that it was logged in.
Obviously I don’t want the site members to all be logged out over the migration. Where should I look or what am I missing here?
The user I’m currently testing has Admin and is using 2FA, and the discourse containers are behind Nginx which terminates SSL, if that makes a difference to the problem.
Thanks in advance for any pointers!
