I realized in early 2014 a site joomla 2.5 with the template CleanOut.
Today I would like to pass it in joomla 3.7.
My question : I don't want to change the template for the moment but simply update the joomla. What do you advise me then?
1) reinstall the siteshaper cleanout with the current version then integrate my data backup inside?
2) or simply update the template by downloading only the current version template?
This is important because I have to do the php update on my server and I'm afraid that my joomla 2.5 does not like much
Thank you in advance for your answers
