Updating joomla to 1 5
Long Version: You will require these 2 packages to update the site for the process of updating from Joomla 3.4.8 to Joomla 3.81. https://downloads.joomla.org/cms/joomla3/3-6-1/joomla_3-6-x_to_3-6-1-stable-patch_package-zip? format=zip Once you have downloaded it then you can apply one of the method from following to update first to Joomla 3.6.0 version.
Updating Joomla version is simple but there are important factors you should note when doing the update.
Good for developers who need to keep reloading site back and forth or before updating something important.
I took a backup finally and tried to play with the site.
I tried and restored the site couple of times, few attempt to update and to be precise I failed 3 times with silly mistakes or trying out with various methods.
Finally, found out the way by reading some of the articles, documentation and github issue comments.
