Drupal commerce donate: Safely update to dev version of module on live site I need to update my charity website to the dev version of commerce donate because we have recently discovered that donors cannot donate decimal amounts with the current recommended release (e.g donate £5.20) and this is something that we need as people need to pay in fundraising money etc. 

I am weary of uninstalling the current module and reinstalling as we have several products that are created using the donation content type and don't want to lose them or the existing donations people have made from the system.

Is there a way to do this safely and (preferably) easily?
If you go through the normal process to update the module (which for me means drush dl --dev commerce_donate in this case - or you might download &amp; un-tar the module directly), no uninstall will be necessary.  In general you should not uninstall a module before installing an update, for exactly the reason you fear.
