It is always wise to back-up one’s website before ANY modification or upgrade – for exactly these kinds of reasons. Also, just because there is a shiny new toy just released, it’s not always the best idea to jump right on it thinking everything will work perfectly right out of the box . . . especially a “beta” version.
If you weren’t aware of this already, please do check out AKEEBA BACKUP[/url]
As for the extension and it’s compatibility with J2.5b1 – as it is a 3rd Party developed extension, this is an issue you would need to discuss with the extension’s developer.
