I have decided to update my development PC to use PhpStorm-2017.1, but before I update, I do not want to end up wasting 1-2 days re-configuring, if there are any potential issues that can hinder my work.
Will my current license work on the new version?
Will my project settings integrate with the update? (Symfony)
Will my plugins settings be kept? (Symfony)
Any other thing I need to figure out?
Official response form JetBrains:
It's hard to tell whether your plugins will work with 2017.1 since there are always some changes in API that may affect some of your plugins. So it's easier just to install 2017.1 and see how it goes. Installation won't broke your existing PhpStorm 2016.2 and its settings.
I believe there have been no changes in license server so if you have right on 2017.1 there shouldn't be any problems.
P.s. Thank you every one for your responses. I will be going with the official answer.
