Hi, I have an OVH dedicated server with: CENTOS 6.5 PLESK 11.5 PHP 5.33 MYSQL 5.1 It has been with those versions since March 2014. I haven't updated it for the last 2.5 years. But now I must updated it because I need PHP 5.6, so I would like to upgrade Plesk from 11.5 to 12.5, and I think when I do that upgrade from plesk panel, php and mysql may update automatically as well. But I want a professional to help me do this because my production server is hosting my apps and it is critical that this upgrade goes well. The plesk panel is giving me the option to upgrade from 11.5 o 12.5, when starting the process there are a couple of warnings that I don't understand, so I need the help of a professional. It should all be straight forward and easy but I prefer to do it together with a professional let me know how much you would charge me for helping me to upgrade my dedicated centos 6.5 server from plesk 11.5 to 12.5, which should also hopefully upgrade php from 5.33 to 5.6 and mysql from 5.1 to 5.5 i guess best Jav

Currently we have built up our server manually and have just documented the process (somewhat). We'd like at least the basis of the application/database server setup in docker and begin migration to AWS for it. We took a small step in serving our assets via Cloudfront but need to finish the job. Our goal is to make sure we have a rapid way to setup additional servers (in case of failure or also regional requirements). We're after a solid remote worker who has completed jobs like this before and we're happy to take some suggestions on board.
