How are Rails projects transferred?

Question

ruby

For example, a situation arose when you need to transfer the site to another vps. How do they proceed in such a case?

Answer 1

The easiest option (if temporary downtime is not critical) is to turn off the old server, start a new one and switch dns.
For more complex options (no downtime), you can set up a new database server and mirror all traffic to the new database. Otherwise, everything is the same, we set up a new server and switch dns.
In both cases, it is better to reduce the TTL in dns in advance.
