SignServer In Place Upgrade

This guide upgrades a single node from SignServer Enterprise version 5.4.0 to SignServer Enterprise 5.5.0. In this example, the SignServer host has an IP Address of 172.1617.130. Change this IP address to be the IP Address that matches the SignServer node being upgraded.

Download the SignServer binary file from your customer download folder or obtain a copy from support at support@primekey.com.

Copy the upgrade package to the SignServer node using one of the following methods:
1. Using the CLI:
  If using a Mac or Linux based computer, use the following command to copy the file to the host. If using AWS, ensure you specify the user as ec2-user with your SSH key and in Azure, specify the user provisioned with your instance.
  scp ~/Downloads/signserver-ee-5.5.0.Final-bin.zip root@172.16.17.130:/opt/dist/
2. Using a program such as WinSCP or CyberDuck:
  Click Open Connection.
  
  Enter the host credentials and click connect.
  
  Select the /opt/dist directory.
  
  Drag and drop the file to the SignServer host in the /opt/dist directory.
SSH to the SignServer host and log in as root.
```
ssh root@172.16.17.130
```
Change directory to the /opt directory.
```
cd /opt
```

Unzip the upgrade file into the /opt/ directory.

unzip dist/signserver-ee-5.5.0.Final-bin.zip

Ensure the file is extracted into the /opt/ directory by doing a directory listing.

[root@signserver-node-01 opt]#

Copy the existing config files to the new SignServer install folder overwriting the default files with the existing files.
```
/bin/cp -f signserver/conf/*.properties signserver-ee-5.5.0.Final/conf/
```
Stop WildFly.
```
systemctl stop wildfly
```
Remove signserver symlink.
```
rm signserver
```
You are asked to remove the symbolic link. Select "y" and press enter.
```
rm: remove symbolic link ‘signserver’?
```

Make sure the command asks you to remove symbolic link.

Create a new symbolic link.

ln -s signserver-ee-5.5.0.Final signserver

Ensure the symbolic link points to the new SignServer directory.

lrwxrwxrwx   1 root    root     16 May 15 17:53 signserver -> signserver-ee-5.5.0.Final

Change the ownership of the new SignServer files. Ensure the trailing "/" in the command below so the permissions of the directory are changed and not the symlink itself.
```
chown -R wildfly:wildfly /opt/signserver/
```

Copy the "signserver.ear" file to the WildFly deployments directory.

/bin/cp -f signserver/dist/signserver.ear /opt/wildfly/standalone/deployments/

Restart Wildfly.
```
systemctl start wildfly
```
Ensure the new version of SignServer is 5.5.0 in the Admin UI.
