Fast 2.3 to 3.0 speed

Question

I have a project that was launched using swift 2 in xcode 7. Now I use swift 2.3 in xcode 8. When I try to switch to pro 3, I get several errors without a project. Both from libraries and from my code. First, I update my pods, and then I automatically convert the project. My doubts: In case some library can cause an error, can I unlock and convert it? Do I have to prepare something before starting a conversation? In the articles I read about it, I did not say anything about it. If you continue to use swift 2.3, will you have any problems in the future?

The application is very large, what would be the best option?
