Hi Darin,
These are common steps to upgrade a JoomlArt template:
– Take complete site backup.
– Update Joomla
+ Check if our template which you’re using is available for the latest version of Joomla or not: we often have blog news or you can check in info page of that template. When Joomla releases a new version, we often check and upgrade our template to make it work with this new version.
+ Update Joomla following recommended methods by joomla.org.
– Update JA Extensions Manager Component to latest version. (downloads available in all the above template’s download folders).
– Update JA T3 Framework Plugin to the latest version (if that template is built along with JA T3 framework).
– Check template download folder for updated complimentary extensions and update the same one by one.
View the comparison between versions at JoomlArt Version Updates and replace the affected files, if you have not customized the affected files.
RECOMMENDED : Use JA extension Manager Component for upgrade. Watch video for how to upgrade using JAEM.
Hope this helps you.
