Following advice of CU have updated the server to centos 7.

To do this a new 500GB SSD was purchased and installed in the enclosure and a clean install of centos7 was installed to this.
An npg account was setup with the same password as previously. Likewise the su password is the same

The existing 500GB HDD can then be mounted using the disk tool in Applications/Utilities/Disks (Requires administrator rights)

The MIDAS_Releases directory was tarballed and coppied across to its respective place on the new install.
A symlink from /MIDAS to this location was created

dhcpd.conf was copied across. dhcp needed to be installed on the machine as well.
/etc/hosts was also required to get the hostnames for the rpis working

oh, GREAT, LayOut, Patrick and analyser directories were also tarballed and moved across

.desktop files have been created for all of the shell scripts used to start the servers.
A gnome extension Frippery panel favourites has also been installed which allows the shortcuts to be stored in the top panel similar to sl6

Early tests appear to be working.

Will test with the FEEs later this week.

Currently the machine is booted into centos but will be booting into sl6 tomorrow to run some tests.
