title: How hard is it to migrate a project from Delphi 7 to Delphi XE?
body: <p>Our company have a software that has been in development for over 10 years, so there are some really dated stuff in there. It's still quite functional and everything, but I see the new features on Delphi XE and it makes me want to switch. Problem is that the source code itself is over 300mb of .pas files (1gb total with components, etc). </p>
  
  <p>We're using custom components, old jvcl stuff and the latest devexpress.</p>
  
  <p>How hard can I expect things to be if I decide to migrate from Delphi 7 to Delphi XE?</p>
  
  <p>Thank you.</p>
