Regarding OS Installation upon Upgrading the System Hardware

Asked by Navin Talati on 2020-10-28

I am seeking your advice and help for the following:
I am to upgrade my system. In that I am to upgrade my Motherboard(Asus ROG Strix B450-F Gaming) and CPU (Ryzen 5 2600) with DDR4 Type RAM and appropriate Graphic Card.
I want to keep my HDDs all the same. In that as O.S. "Ubuntu 18.04 LTS" is already installed during the previous configuration. (i.e. Motherboard: Saus M4A88T-M, CPU: AMDs Phenom (tm) II X2 555, RAM:DDR3 and Graphic Card; GT520 Silent 2GB DDR3 nvidia GeForce)
In new configuration , I want to go for UBUNTU 20.04 LTS.
My question is: Can the OS get upgraded directly OR I need to reinstall a fresh in that?
Please, guide me.
Thanks to all in anticipation.

The two actions (new hardware and release upgrade) are independent of each other. The sequence should not matter. Its's your choice whether you try the release upgrade first and then plug the hard disk into the new motherboard, or you can do it the other way round. The Ubuntu system should be clever enough to identify the drivers required for the current hardware in place at that moment.

From the reply above, I understand that I need not make a fresh installation on my existing HDDs. Straight way I can connect the HDD in the new upgraded system and it will take up the required drivers automatically and will run as it was running in the pre-upgraded status. Then I can upgrade the distro.

Is my understanding correct.

If not, kindly oblige me by rectifying the proposed procedure. Please.

It is one of the concepts that this should work. Nevertheless no warranty can be given. Just try. If it fails for whatever reason, you still have the possibility for a new install.
