Joomla!5 was released at the same time as Joomla!4. The changes are marginal compared to the upgrade from Joomla!3 to 4. Major problems are not expected with the update, but extensions are often not yet Joomla!5 compatible.

You don't want to do the upgrade to Joomla!5 yourself?

I will gladly do this for you! Benefit from my experience through numerous successfully performed Joomla!5 upgrades.
