On the 22nd of April, 2021, Canonical released Ubuntu 21.04 with the nickname ‘Hirsute Hippo’ – which comes with new features dedicated to developers and innovators. It comes with Flutter application development SDK and Microsoft SQL Server for Ubuntu. In addition, this latest Ubuntu release comes with native Active Directory, integrated within it and Wayland graphics. Ubuntu 21.04’s Linux kernel ships Wayland with some suitable shots of appearance tweaks, software updates, and performance enhancements. Currently, if you are running using older versions of Ubuntu like Ubuntu 20.04 (Focal Fossa) or Ubuntu 20.10 (Groovy Gorilla) and wish to upgrade to Ubuntu 21.04 directly, this article is for you.
Note that Ubuntu 20.04 is a stable release with long-term support (LTS). This version of Ubuntu will support your system for five years. On the other hand, Ubuntu’s new release (21.04) is non-LTS. It will stay in your system for nine months only. Therefore, if you prefer the stable release over new enhancements, do not upgrade your system.
Do’s and Don’ts
Before you start the upgrade process, keep all these critical points in mind. It will help prevent your system from crashing or losing your data.
· Make sure you back up all the data and personal files in cloud storage or any other USB drive. It will help you revive your data if the upgrade fails or crashes.

· Experts recommend keeping a Live USB drive on standby in case your system crashes while performing the upgrade. The Live USB stick of your old Ubuntu 20.10 or 20.04 would revert to your system if anything went wrong during the transition.
