## Preparation

### Single Node versus Multi-Node

This procedure is written for systems that follow standard single-node deployment architectures. For advanced deployments see [[server:upgrades#multiple_node_upgrades|Multiple Node Upgrades]].

### Backup Appliance and Database

Start by backing up the appliance. The upgrade to will be an upgrade of both software and the database. Please do not proceed without a good backup. The upgrade does not support a database rollback, so if something does not go to plan, a system restore will be required.
### Service Window

Upgrades must be performed during service windows. User access to the Access Anywhere Server should be suspended during the service window. The server upgrade from 2401 should take under 20 minutes.

### Server Upgrade

Log into the appliance via SSH as smeconfiguser e.g.

    ssh smeconfiguser@naa.example.com

Switch to the root user

    su -

Stop services

    systemctl is-enabled crond && systemctl stop crond && echo 'Stopped Cron'
    systemctl is-enabled httpd && systemctl stop httpd && echo 'Stopped HTTPD'

Apply software updates

    yum clean all
    yum update sme-externalrepo
    yum install sme-package-2401.0.1

and to update third-party components

    yum update

Now please reboot the system.

   reboot

### Recommended Settings

The following setting have been changed to increase sync performance for new instances. For your existing installations, we recommend increasing the number of processing threads from 2 to 4 if you have not changed these before. To increase from 2 to 4, run the following as root:

    ((ffconfig getval initialsyncthreads | grep -w 2) > 2&>1) && (echo 'Increasing from 2 to 4' && ffconfig set initialsyncthreads 4 2&>1) || echo 'Value is already overridden. Skipping'
