Remotely close & rerun SSH connection

I'm trying to remotely run an upgrade script (via SSH) that update the SSH script on several hosts, just need to add several flags for the ssh command to look like this:

Code:
ssh -Nf -i id_logs -o ExitOnForwardFailure=yes -o StrictHostKeyChecking=no -o ServerAliveInterval=60 -o ServerAliveCountMax=5 -R <port>:127.0.0.1:22 <user>@<host>

after successfully update the SSH script located on the remote hosts I want to restart the SSH process, then reconnect again to check the new connection has established successfully - my problem is that after I kill the SSH process I get kicked out of the host, and obviously can't rerun the SSH tunnel,

I was thinking of running another local script with sleep of 10seconds before killing the SSH process that will recover the SSH..but that doesn't work.
Does anyone has a good solution ? I think my idea is a bit primitive..there must be a better way to do it.

thanks !

NAME
ssh-argv0 -- replaces the old ssh command-name as hostname handling SYNOPSIS
hostname | user@hostname [-l login_name] [command] hostname | user@hostname [-afgknqstvxACNTX1246] [-b bind_address] [-c cipher_spec] [-e escape_char] [-i identity_file] [-l login_name] [-m mac_spec] [-o option] [-p port] [-F configfile] [-L port:host:hostport] [-R port:host:hostport] [-D port] [command] DESCRIPTION
ssh-argv0 replaces the old ssh command-name as hostname handling. If you link to this script with a hostname then executing the link is equivalent to having executed ssh with that hostname as an argument. All other arguments are passed to ssh and will be processed normally. OPTIONS
