How do I move my project save to a past release of a scirra update

I wanted to move my project save to r259 right now I have my project in r260.

Edit the CAPROJ file. Change the element:

<saved-with-version>26000</saved-with-version>

to

<saved-with-version>25900</saved-with-version>

Edit the CAPROJ file. Change the element:
