TOPIC: Upgrading to a new version 3.26 - 4.0 alpha2

I would like to know how to upgrade to a newer, and tried to upload the new component, but gives me error, what would the perfect way to update the version.

Gracias

Hey Subly,
Please don't upgrade to 4.0 alpha 2. This version is not for production sites. It is only for testing purposes.

If you at the end still wish to make it - just uninstall the old version and install the new one. But please, wait at least for beta1.

Ok thanks, how long does it take more or less in the final draw?

Less, I'm hardly working on it. You can test the alpha on your configuratin, share the problems you have with it so we get everything fixed for the final release.
