Update Joomla 2.5.x to 3.x with shoes template

Good afternoon, we need to migrate to Joomla 3.x template shoes from 2.5, what is the best way to do it.

Thank you very much.

Greetings.

Go to Joomla!Update option in your backend. Click on options. Set update server "Short Term Support". Save, and return to control panel. Refresh periodically until option to update to j3 is shown. That go ahead...

NOTE: ALL OF YOUR EXTENSIONS NEED TO BE J3 COMPATIBLE ALSO, you need to work on that first. J3 will turn them off

Good night.

I am clear that all extensions must be compatible with joomla 3.x

I have made the setting "Short term support" and appears on the screen that I can upgrade to 3.3.6

Wonder timely measures must take into account the shoes template, when you upgrade the Joomla.

I do not understand what turning off the J3

Forgive my ignorance.

Thank you very much.

Greeting.

J3 will turn off non-compatible extensions on update.
As for template you need to replace template files with files from template j3 version.
