Preventing file compiler during 2.x to 3.x upgrade?

[MarcC]

Hi all,

Am I correct in remembering that adding a namespace statement to the top of every template file will prevent the file compilation process from needing to run during a 2.x to 3.x upgrade? 

I had attempted this same upgrade previously on a site with many pages, but the upgrade seemed to fail. However, afterwards I realized it may have been the delay in compiling files rather than a failure of the upgrade. So I'd like to avoid the compilation process if possible.

Thank you for any tips! --Marc

Oh funny, thanks. That's a pretty clever way to manage the configuration. So in case anyone else is wondering, it seems you can either add a namespace to your template files or just set $config->templateCompile to false in config.php. I do wonder what the implications are for either choice, or how future-proof it is to set this to false instead of adding the namespace.
