I'm running a rather old version of OLS on my server (v1.2.6) and I'm interested in upgrading to the latest version. I have a couple of websites running on this server and I was wondering if it was possible to update to the latest version of OLS without losing my current data or do I have to make a clean installation (and lose my current data)? By current data I mean my OLS settings, databases, website files, etc. If it is possible to upgrade without losing the data, I'd appreciate if you guys can point me in the right direction to do this. If it's not possible to upgrade without losing the data, is there a noticeable benefit to upgrading to the current version vs keeping the old one? OLS is installed on CentOS 6.9 on my server BTW. I hope I explained my situation well (English is not my first language). Thanks in advance.
