I need to move my master postgresql deployment to a new server.

I am comfortable with stopping all connections then doing a pg_dumpall > 
psql to move the databases, they are not huge so this completes in an 
acceptable time and I am not expecting any data loss but I am unsure of 
what impact this will have on the streaming replication.  I will be 
rebooting the new server with the old servers network configuration so I 
am hoping that when I let connections back in, replication will just 
restart but I cant find any documentation that says so.

Currently the slave serves as a read-only target for various services so 
they should all just keep running.

The postgresql versions are 10.20 on the old and 10.17 on the new. 
(Basically this is a CentOS7 to Rocky8 migration) I have been using the 
PGDG rhel version so it is a little ahead of the appstream

Comments ?
