Just try to compile and then test the code, fix anything that doesn't work. 只需尝试编译然后测试代码，修复所有无效的内容。
You don't have to use the new features just because they are there. 您不必使用这些新功能，只是因为它们的存在。
Why upgrade to 5 though? 为什么要升级到5？ You should go to 7 really if going through the pain of doing an upgrade as the extra pain will be very small and you will be up to date for longer. 如果经历升级的痛苦，那么您确实应该达到7，因为额外的痛苦会很小，并且您将拥有更长的更新时间。
