Question:
We are upgrading from an older version of Spectrum to the latest version but as part of this process we need to upgrade the host Operating System first- Is this ok to do
 
Answer:
In a situation where the current Operating System (OS) doesn’t meet the install requirements for a newer version of Spectrum that you are upgrading to you should be able to upgrade the host OS first without any impact to the Spectrum install.
As a precaution you should take a backup of the following (though they should not be impacted by the upgrade of OS if the upgrade is done correctly):
 
  1. SSdb
  2. DDMdb
  3. $SPECROOT/custom directory.
 
Another option in this scenario where an upgrade of the host system is required would be to consider migrating to a new machine with the new OS already installed.
