Upgrade Symfony or drop it?


New Member
Hello, I have a question regarding symfony. My company uses a web application from simplethings, that's based on symfony 2.8, PHP 7 and using claranet as the host. As you can see that version is way too old and simple things now discontinued the support. That poses a safety risk for us. Truth be told, I'm not really proficient in this topic, so I'm asking here:

What would you recommend for us to do? Can we upgrade ourselves or should we totally drop symfony and move to another framework?

Thanks in advance!
