Upgrading from OpenSUSE 13.2 to OpenSUSE Leap

How to Upgrade from  OpenSUSE 13.2 to OpenSUSE Leap..

OpenSUSE UpgradeWhen I decided to upgrade from OpenSUSE 13.2 to OpenSUSE Leap, I found that I could not upgrade directly because my OpenSUSE 13.2 was a 32 bit installation, whereas the OpenSUSE Leap is a 64 bit installation.

My work environment consists of a Laptop with Windows 8,1, Oracle VirtualBox and my OpenSUSE installation as a virtual machine of VirtualBox.

I think that this is a satisfactory setup because it allows me to access Windows and OpenSUSE applications at the same time and removes the risks of problems during double booting with Grub that I had experienced in the past,

In order to install the OpenSUSE Leap without risks for my working working environment, I decided to create a new virtual machine with the new Operating System.

I will describe below my approach and I would be interested to receive comments and suggestions on alternative ways to do the work,

Addition of the Virtual Machine in VirtualBox

The creation of a new virtual machine and the installation of OpenSUSE Leap is described pretty well in the article  How to install openSUSE Leap 42.2 in VirtualBox and I will describe only the main steps:

  • Open VirtualBox and create a new virtual machine. Select Linux type and openSUSE version
  • Select the amount of memory RAM. They recommend 4096 MB (4 GB), but I found that the machine works well also with 3 MB.
  • Create a new Virtual Disk (since I have plenty of data I created a VDI disk with 200 GB
  • We have created a new empty virtual machine. We need to set more properties and read the lSO file. You can find in the article a goof description of the settings, then load the openSUSE ISO file in the Storage tab of the Virtual Machine.
  • Finally Start the Virtual Machine and choose the Installation option to install OpenSUSE Leap

After the installation I took a snapshot of the virtual machine and then performed an online update of OpenSuSe  by using Yast,

Copying the Data from the Old to the New Virtual Machine

I decided to use the tar command to copy the relevant directories from my old OpenSUSE 13.2 machine to the new OpenSUSE Leap machine.

I created separate tar archives for my home directory and many directories containing data by using commands such as:

tar -cvzf  archive-name .

In order to transfer the archive file to the new virtual machine, I defined a common shared folder created in the Windows installation.

I just moved the tar archives of the old virtual machine to the shared folder and then I could easily access them from the new virtual machine and move them to the target directory,

For each archive I restored the data in the appropriate directory by running a command such as the following:

tar -xvzf  archive-name .

Strange Problems After the  Installaion

After the installation I had to face some problems as described below:

 

a) My Samsung ML-1640 usb printer did not work in Opensuse Leap,

I realized that USB drives are not automatically detected by VirtualBox, but must be added manually. In addition, I also had to add the VirtualBox groups to the user of the system in order to correctly access the USB drive.

 

b) I had frequent  memory reference errors in VirtualBox that caused a crash of the virtual machine. I tried to re-install OpenSUSE without any improvements.  Finally I realised that the problem had after the addition of the usb devices (the printer and an external disk). I tried to remove the external disk and the system has worked well after that.

 

 

Conclusions

The installation has taken some time, but it works pretty well.s

Even if the two virtual machine have more or less the same resources (about 3 GB of memory), the OpenSUSE Leap is significantly faster than my old  OpenSUSE 13,2. and of course there is also the advantage of using the latest versions of the programs
