There are a few things to know and consider for updating the system. Please read carefully!

== Important Upgrade Notes: Major OS upgrade ==
This update is making a '''major OS upgrade''' of your regify provider. The CentOS 6 system is updated to CentOS 7.5, which requires a few reboots and SSH re-logins. It also takes some more time than a normal patch update (6 to 15 minutes, mainly depending on your system speed).

== <span style="color:#990000;">Important ToDo before upgrading! READ ME</span> ==
=== More RAM for the Virtual Machine ===
For the upgrade to work, the VM must have '''at least 2GB of RAM'''. If you do not yet have 2GB RAM assigned, you may want to shutdown the machine (shutdown -h now) and re-assign some more memory before you switch it back on and start the upgrade.

=== If you're using the NAGIOS capabilities ===
Please note that ''/etc/nagios/nrpe.cfg'' will be overwritten and '''nrpe''' will not run after the upgrade. You may want to make notes of the needed settings before upgrading.

=== If you installed third party tools like VMWare-Tools, Backup-Tools etc ===
Please note that other running demons and scripts might crash the upgrade. Please stop all running third party demons and scripts which are not original by regify. In case of doubt, remove them prior to the upgrade! Please also note that, due to all our documentation and contracts, we are not reliable for any issues caused by such third party software. Maintenance efforts due to such issues will be charged. In general, we strongly suggest to not run any third party tools at all (not even virtualization or backup tools)! Virtualization tools are not required at all.

=== Make a snapshot shortly before upgrading ===
In order to be able to rollback a failed upgrade, please make a snapshot of your virtual machine(s) shortly before starting the upgrade.

=== IMPORTANT: Read the dialogues during update! ===
<span style="color: #770000;">If dialogues or notes coming up during update, please READ them carefully and follow instructions!</span>

== Starting the upgrade ==
To update your regigate appliance, please log in via SSH (PuTTY) and select the first menu item "Check for updates". The update process can take up to 15 minutes. If you are running a redundant system (floating IP), you first have to break the connection between the two systems. After the upgrade of both systems, you can re-establish redundancy.

== ToDo after upgrading ==
=== RAM for the Virtual Machine ===
Maybe you like to shutdown (shutdown -h now) and set RAM size back to what it was before (eg 500MB or more)?

=== If you created snapshots, remove them ===
In case you created a snapshot before update, you might consider removing it. If everything went fine, a fresh snapshot of the updated system makes more sense.

=== If you're using the NAGIOS capabilities ===
You have to re-setup NAGIOS modules and configuration after the update. Please use the notes you've taken before.
