tar -C / -xzvf smeserver.tgz

If the Lets Encrypt Contrib is installed...

config setprop letsencrypt status disabled

config delprop modSSL key
config delprop modSSL CertificateChainFile

Then...

/sbin/e-smith/signal-event post-upgrade

and after rebooting...

cd /
rm smeserver.tgz

May need to reconfigure server and set to a static external IP address!
